John Trapp on Psalms 13:3

Verſ. 3. Conſider and hear mee O Lord my God] Hee turns him to God in this peck of troubles (for they ſeldome come ſingle) and pleads the Covenant, My God; beſeeching him to ſee and hear both at once, how it fared with him, and to ſend him feaſonable and ſuitable ſuccour. It were wide with the faithfull, if they had not their God to repair unto in diſtreſſe, pouring out their ſouls into his bleſſed boſome. This they muſt do moſt earneſtly, when under a cloud of deſertion; as our Saviour being in an agony prayed more fervently, Luk. 22.44. and as Micah having loſt his Gods, ſet up his Note, Judg. 18.

Lighten mine eyes leſt I ſleep death] i. e. Comfort my conſcience, clear up my condition, and chear up my drooping ſpirit, leſt I faint away as a dying man, whoſe eyes through weakneſſe wax dimme; leſt I fall into that ſomnus ferreus, as the Poets call death, that longeſt ſleep; Surge, ne longus tibi ſomnus unde Non times, detur.Mor.lib.3.[illegible: 1 letter] 11.
