Yahweh does not sleep (Ps 121:3-121:4)

“Yahweh will not let your foot be moved.

He keeps you.

He will not slumber.

He who keeps Israel,

Will neither slumber nor sleep.”

Yahweh is vigilant. He will not let the Israelite feet be moved. He keeps them safe. He will not sleep nor will be slumber. The vigilant Yahweh will protect Israel and the Israelites.
