Psalm 127:1 says a human watchman stays awake in vain without the Lord—highlighting the reliability of God's never-sleeping guard.

1 Kings 18:27 mocks Baal as possibly asleep—a direct contrast to Yahweh, who never slumbers or sleeps.

Isaiah 27:3 repeats the promise: the Lord keeps His vineyard night and day, never ceasing—matching the never-slumbering Keeper of Israel.

Numbers 6:24 contains 'The LORD keep you'—the same Hebrew verb (shamar) used for the Keeper who never slumbers.
