Psalms 140:12

“I know, etc.] Here is a double reading: the “Keri”, or marginal reading, is, “thou knowest”; an appeal of the psalmist to God, who knew the thoughts of the wicked concerning him, and their devices against him; as Kimchi: but the Scripture reading is, I know; expressing his full persuasion and assurance that the Lord will maintain the cause of the afflicted, [and] the right of the poor; of his poor and afflicted people, that are afflicted within and without, by men and devils; and who are poor as to the things of this world, and poor in spirit, and sensible of their spiritual poverty, but rich in grace: the cause of these God will maintain against their oppressors, and right their wrongs, and…”

“I know that the Lord will maintain the cause of the afflicted - See the notes at Psalms 9:4. The psalmist here doubtless refers primarily to himself, as having a confident belief that the Lord would maintain “his” cause, or would defend “him.” At the same time he makes the statement general, implying that what would be done to him would be done to all in similar circumstances.

“With Psa 140:13 the mood and language now again become cheerful, the rage has spent itself; therefore the style and tone are now changed, and the Psalm trips along merrily as it were to the close. With reference to ידעת for ידעתי (as in Job 42:2), vid., Psa 16:2. That which David in Psa 9:5 confidently expects on his own behalf is here generalized into the certain prospect of the triumph of the good cause in the person of all its representatives at that time oppressed. אך, like ידעתּי, is an expression of certainty. After seeming abandonment God again makes Himself known to His own, and those whom they wanted to sweep away out of the land of the living have an ever sure dwelling-place with…”
