Psalms 69:2

“I sink in deep mire, where [there is] no standing, etc.] 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 “<194002>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, (<421250>Luke 12:50), when he was as one immersed in and overwhelmed with water.”

“I sink in deep mire - Margin, as in Hebrew, “the mire of the depth.” This would denote either mire which was itself so deep that one could not extricate himself from it; or, mire found in a deep place, as at the bottom of a pit. Compare the notes at Psalms 40:2. An illustration of this might be drawn from the case of Joseph, cast by his brethren into a deep pit Genesis 37:24; or from the case of Jeremiah, thrown into a deep dungeon: “And they let down Jeremiah with cords; and in the dungeon there was no water, but mire: so Jeremiah sunk in the mire,” Jeremiah 38:6. Where there is no standing - No solid ground; nothing for the foot to rest on. “I am come into deep waters.” Margin, as in…”

“I sink: Psa 40:2; Jer 38:6, Jer 38:22 deep mire: Heb. the mire of depth deep waters: Heb. depth of waters, Psa 88:6, Psa 88:7; Eze 27:26-34 the floods: Psa 32:6; Gen 7:17-23; Mat 7:25, Mat 26:37, Mat 26:38 Psalms 69:3”
