Verse 2. - I sink in deep mire, where there is no standing. "Mire" and "clay" are metaphors for dangers and difficulties, which entangle a man and incapacitate him from exertion (comp. Psalm 40:2). I am come into deep waters (comp. ver. 15; and see also Psalm 124:4, 5; Psalm 130:1). Where the floods overflow me; i.e. "I am utterly overwhelmed by my misfortunes."

69:1-12 We should frequently consider the person of the Sufferer here spoken of, and ask why, as well as what he suffered, that, meditating thereon, we may be more humbled for sin, and more convinced of our danger, so that we may feel more gratitude and love, constraining us to live to His glory who died for our salvation. Hence we learn, when in affliction, to commit the keeping of our souls to God, that we may not be soured with discontent, or sink into despair. David was hated wrongfully, but the words far more fully apply to Christ. In a world where unrighteousness reigns so much, we must not wonder if we meet with those that are our enemies wrongfully. Let us take care that we never do wrong; then if we receive wrong, we may the better bear it. By the satisfaction Christ made to God for our sin by his blood, he restored that which he took not away, he paid our debt, suffered for our offences. Even when we can plead Not guilty, as to men's unjust accusations, yet before God we must acknowledge ourselves to deserve all that is brought upon us. All our sins take rise from our foolishness. They are all done in God's sight. David complains of the unkindness of friends and relations. This was fulfilled in Christ, whose brethren did not believe on him, and who was forsaken by his disciples. Christ made satisfaction for us, not only by putting off the honours due to God, but by submitting to the greatest dishonours that could be done to any man. We need not be discouraged if our zeal for the truths, precepts, and worship of God, should provoke some, and cause others to mock our godly sorrow and deadness to the world.I sink in deep mire, where there is no standing,.... Which signifies not despair of mind, but difficult and distressed circumstances; the Messiah now bearing the filthy sins of his people, and the punishment of them, and so was got into the horrible pit, the mire and clay; See Gill on Psalm 40:2;

I am come into deep waters, where the floods overflow me: as afflictions are often compared to waters in Scripture, Christ's sorrows and sufferings are very aptly signified by deep waters and overflowing floods; and therefore rightly called a baptism, as by himself, Luke 12:50, when he was as one immersed in and overwhelmed with water.
