How long wilt thou forget me, O LORD? for ever? how long wilt thou hide thy face from me?

1. The forms of expression and figure here used are frequent (compare Psalms 9:12; Psalms 9:18; Psalms 10:11; Psalms 10:12).
How long . . . for ever—Shall it be for ever?

2.

How long shall I take counsel in my soul, having sorrow in my heart daily? how long shall mine enemy be exalted over me?

2. The counsels or devices of his heart afford no relief.

3.

Consider and hear me, O LORD my God: lighten mine eyes, lest I sleep the sleep of death;

3. lighten mine eyes—dim with weakness, denoting approaching death (compare 1 Samuel 14:27-29; Psalms 6:7; Psalms 38:10).

4.

Lest mine enemy say, I have prevailed against him; and those that trouble me rejoice when I am moved.

4. rejoice—literally, "shout as in triumph."
I am moved—cast down from a firm position (Psalms 10:6).

5.

But I have trusted in thy mercy; my heart shall rejoice in thy salvation.

5, 6. Trust is followed by rejoicing in the deliverance which God effects, and, instead of his enemy, he can lift the song of triumph.

6.

I will sing unto the LORD, because he hath dealt bountifully with me.
