(2) Whom thou knowest.--The pronoun is emphatic. The twelve spies, two of whom were still living, had seen them (Numbers 13:33), and their fame was doubtless notorious. It seems to have been a common saying, possibly among the Anakim themselves, "Who will stand up to the children of Anak?" No one could be found to face them.

Verse 2. - Anakim (cf. Deuteronomy 1:28). It was a common saying, Who can stand before the sons of Anak? But even these gigantic foes should be unable to stand before Israel (cf. Deuteronomy 7:24):

9:1-6 Moses represents the strength of the enemies they were now to encounter. This was to drive them to God, and engage their hope in him. He assures them of victory, by the presence of God with them. He cautions them not to have the least thought of their own righteousness, as if that procured this favour at God's hand. In Christ we have both righteousness and strength; in Him we must glory, not in ourselves, nor in any sufficiency of our own. It is for the wickedness of these nations that God drives them out. All whom God rejects, are rejected for their own wickedness; but none whom he accepts are accepted for their own righteousness. Thus boasting is for ever done away: see Eph 2:9,11,12.A people great and tall,.... Of a large bulky size, and of an high stature, so that the spies seemed to be as grasshoppers to them, Numbers 13:33,

the children of the Anakims, whom thou knowest; by report, having had an account of them by the spies, who described them as very large bodied men, and of a gigantic stature, the descendants of one Anak, a giant; and so the Targum of Jonathan,"a people strong and high like the giants;''from these Bene Anak, children of Anak, or Phene Anak, as the words might be pronounced, the initial letter of the first word being of the same sound, Bochart (z) thinks the country had its name of Phoenicia:

and of whom thou hast heard say, who can stand before the children, of Anak? or the children of the giants, as the Targums of Onkelos and Jonathan; which they had heard either from the spies who had suggested the same, Numbers 13:31 or as a common proverb in the mouths of most people in those days.
