Psalms 13:3

“Consider [and] hear me, O Lord my God, etc.] The psalmist amidst all his distresses rightly applies to God by prayer, claims his interest in him as his covenant God, which still continued notwithstanding all his darkness, desertions, and afflictions; and entreats him to “consider” his affliction and trouble, and deliver him out of it; to consider his enemies, how many and mighty they were; and his own weakness his frame, that he was but dust, and unable to stand against them: or to “look” f219 upon his affliction, and upon him under it, with an eye of pity and compassion; to have respect to him and to his prayers, and to turn unto him, and lift up the light of his countenance upon him: and…”

“lighten mine eyes--dim with weakness, denoting approaching death (compare Sa1 14:27-29; Psa 6:7; Psa 38:10).”

“Consider and hear me - literally, “Look, hear me.” God had seemed to avert his face as if he would not even look upon him Psalms 13:1; and the psalmist now prays that he “would” look upon him - that he would regard his wants - that he would attend to his cry. So we pray to one who turns away from us as if he were not disposed to hear, and as if he cared nothing about us. Lighten mine eyes - The allusion here is, probably, to his exhaustion, arising from trouble and despair, as if he were about to die. The sight grows dim as death approaches; and he seemed to feel that death was near. He says that unless God should interpose, the darkness would deepen, and he must die. The prayer, therefore,…”

“Lighten - Revive and comfort, and deliver me from the darkness of death, which is ready to come upon me. Psalms 13:6”

“13:3-4 Only the Lord can bring enlightenment and relief. The psalmist longs for the Lord’s vindication so that his foes will not rejoice. 13:3 The psalmist’s affliction feels like death (22:15; 55:4; 88:15; 94:17; 116:3).”

“Consider: Psa 9:13, Psa 25:19, Psa 31:7, Psa 119:153; Lam 5:1 lighten: Psa 18:28; Sa1 14:27, Sa1 14:29; Ezr 9:8; Luk 2:32; Rev 21:23 lest: Jer 51:39, Jer 51:57; Eph 5:14 Psalms 13:4”

“(Heb.: 13:4-5) In contrast to God's seeming to have forgotten him and to wish neither to see nor know anything of his need, he prays: הבּיטה (cf. Isa 63:15). In contrast to his being in perplexity what course to take and unable to help himself, he prays: ענני, answer me, who cry for help, viz., by the fulfilment of my prayer as a real, actual answer. In contrast to the triumphing of his foe: האירה עיני, in order that the triumph of his enemy may not be made complete by his dying. To lighten the eyes that are dimmed with sorrow and ready to break, is equivalent to, to impart new life ( Ezr 9:8), which is reflected in the fresh clear brightness of the eye ( Sa1 14:27, Sa1 14:29).
