Nod in the Bible

And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.

I also, like you, might speak, If your soul were in my soul's stead. I might join against you with words, And nod at you with my head.

All passing by the way clapped their hands at thee; they hissed, and they will nod their head at the daughter of Jerusalem: This the city, they will say; the complete splendor of joy to all the earth.

And the slain shall fall in your midst, So shall ye nod that I a Yahweh.
