(15) Tyre shall be forgotten seventy years.--If we take the number literally, the seventy years may coincide with those of the captivity of Judah, during which, under the Chaldaean supremacy, Tyre was reduced to a state of comparative insignificance. It seems better, however, with Cheyne, to take it as a symbolic number for a long period of indefinite duration, and so, bringing it into closer connection with the context, to reckon the period from its conquest by the Assyrians.

According to the days of one king.--We look in vain for any ruler of Assyria or Babylon whose reign was of this length, and the words probably mean, as the days fixed by a king--i.e., by a despotic and absolute decree. Possibly, however, the "one king" may stand for one dynasty.

Shall Tyre sing as an harlot.--Literally, there shall be to Tyre as the song of the harlot, possibly referring to some well-known lyric of this type. The commercial city, welcoming foreigners of all nations as her lovers for the sake of gain, is compared to the prostitute who sells herself for money. (Comp. Revelation 17:2.)

Verses 15-18. - TYRE'S RESTORATION TO PROSPERITY AND CONVERSION TO JEHOVAH. After an interval, expressed by the symbolic number of" seventy years," Tyre is to rise from her ashes, and become once more a prosperous state, resuming her former occupation of a "merchant city," and once more making great gains, which she will devote to the service of Jehovah. St. Jerome thought that this prophecy had not been accomplished in his day. If so, it cannot be said to have been accomplished yet; unless, indeed, Tyre may be regarded as representing the commercial spirit, which. under Christianity, is not necessarily alien from religion, but shows itself sometimes altogether friendly to the Church, supplying ways and means for ten thousand philanthropic and praiseworthy enterprises (ver. 18). Verse 15. - Tyro shall be forgotten; i.e. "shall cease to occupy men's thoughts, as a factor in politics - shall pass out of their calculations, and count for nothing." Seventy years. "Forty years" and "seventy years" are the chief representatives in Scripture of an indefinite time. The week of creation seems to have given to seven its quasi-sacred character, which passed from the primary number to the corresponding decimal one. The sacred use of "seventy" appears first in the "seventy elders" who accompanied Moses to the covenant-feast on Sinai (Exodus 24:9). After this, "seventy 'talents are mentioned as the weight of the bronze offerings for the tabernacle (Exodus 38:29), and "seventy" shekels as the weight of the silver bowls offered by the heads of tribes when the tabernacle was set up (Numbers 7:13-85). The "indefinite" us, of "seventy" is most apparent in such expressions as that of Genesis 4:24, "If Cain shall be avenged sevenfold, surely Lamech seventy and sevenfold;" and that of Matthew 18:22, "I say not unto thee, Until seven times: but, Until seventy times seven." "Seventy" seems also to be indefinite in Exodus 15:27; Numbers 33:9; Judges 1:7; Judges 12:13; 2 Samuel 24:15; 1 Kings 5:15: 1 Chronicles 21:14, etc. It is absurd to count the "seventy years" of the present passage, as some do, from the accession of Nebuchadnezzar to the death of Nabonidus, for neither did Tyro begin to be forgotten in the first year of the one prince, nor did she immediately recover herself on the death of the other. According to the days of one king; or, like the days of one king. The period, whatever its length, should be to Type "like the days of one king;" i.e. unchanging, without hope. Oriental kings prided themselves on maintaining an unaltered policy (cf. 2 Kings 25:27; Isaiah 14:17). Shall Tyre sing as an harlot; literally, it shall be to Tyre as [in] the song of the harlot. A particular song seems to be meant, part of which the prophet proceeds to quote in the next verse.

23:15-18 The desolations of Tyre were not to be for ever. The Lord will visit Tyre in mercy. But when set at liberty, she will use her old arts of temptation. The love of worldly wealth is spiritual idolatry; and covetousness is spiritual idolatry. This directs those that have wealth, to use it in the service of God. When we abide with God in our worldly callings, when we do all in our power to further the gospel, then our merchandise and hire are holiness to the Lord, if we look to his glory. Christians should carry on business as God's servants, and use riches as his stewards.And it shall come to pass in that day,.... When Tyre is destroyed, from that time forward:

that Tyre shall be forgotten seventy years; shall so long lie in its ruin, and not be rebuilt; it shall be without inhabitants, and unfrequented by men; there shall be no merchandise in it during that time; no merchants will come nigh it; she will be like a harlot cast off and forgotten by her lover: the term of time is the same with that of the captivity of the Jews in Babylon, and great part of it at least run out along with it; for Tyre was destroyed by Nebuchadnezzar, as Jerusalem was, though some time after it, and was restored when the Babylonish empire was destroyed, at the expiration of seventy years:

according to the days of one king; or kingdom, the Babylonish kingdom, which lasted so long in Nebuchadnezzar's family; whose family, he himself, his son, and son's son, are here meant, as Aben Ezra thinks; and seems to be the more commonly received sense; though Kimchi and others understand it of the days of a man, which are seventy years, Psalm 90:10 and so it is added in the Septuagint version, "as the time of a man"; which perhaps was a marginal note, way of explanation, and crept into the text. Jarchi is of opinion King David is meant, whose age was seventy years, though he is at a loss to give a reason for this his opinion; but Kimchi suggests one, and that is, the covenant which was between Hiram king of Tyre and David; and this is mentioned to put the Tyrians in mind of the breach of it, which had brought desolation upon them; some understand this of the King Messiah (i):

after the end of seventy years shall Tyre sing as an harlot; being rebuilt and restored to its former state; as a harlot who has been cast off by her lovers, on account of some disease she has laboured under, and through a dislike of her; but, having recovered her health, makes use of her arts, and this among others, to sing a song, in order to draw, by her melodious voice, her lovers to her again; and so Tyre being built again, and out of the hands of its oppressors, and restored to its former liberty, should make use of all arts and methods to recover her trade, and draw merchants from all parts to her again.
