John Gill Commentary Psalms 69:14

"Deliver me out of the mire, and let me not sink: Let me be delivered from them that hate me, and out of the deep waters." — Psalms 69:14 (ASV)

Deliver me out of the mire, and let me not sink
In which he was sinking, (Psalms 69:2) ; and accordingly he was delivered out of it, (Psalms 11:2) ; even out of all the mire of sin, the sins of his people that were upon him, from which he was justified when raised from the dead; and so will appear without sin, when he comes a second time:

let me be delivered from them that hate me, and out of the deep
waters ;
these phrases design the same, even the enemies of Christ; such that hated him, compared to deep waters: these are the floods of the ungodly, and the many waters out of which he was drawn and delivered, (Psalms 18:4Psalms 18:16Psalms 18:17) .
