Psalms 121:4

“Behold, he that keepeth Israel shall neither slumber nor sleep.] He that kept Israel or Jacob, when asleep, and appeared to him in a dream, and promised to keep him in all places, and did; who found his posterity in the wilderness, and kept them as the apple of his eye: he keeps his spiritual Israel, whom he has chosen, redeemed, and calls; and he that is in general their keeper, is the keeper of every particular believer, who may promise themselves the utmost safety under his care; since, though he may sometimes seem to sleep, when he withdraws his gracious presence, defers help, and does not arise so soon to the assistance of his people as they wish for and expect; yet does not in reality…”

“121:4-6 The Creator (121:2) is the guardian of Israel. • God stands beside Israel, supporting and caring for the godly (see 16:7-8). • Both the sun and the moon were regarded as deities in the ancient Near East, but the Creator limits their power. They, too, praise the Lord (148:3). 121:4 God watches over his own, even and especially when they face many troubles (12:5, 7; 69:29; 91:14; 146:9).”
