Exodus 3:18

They will listen to your voice, and you shall come, you and the elders of Israel, to the king of Egypt, and you shall tell him, 'Yahweh, the God of the Hebrews, has met with us. Now please let us go three days' journey into the wilderness, that we may sacrifice to Yahweh, our God.'
Exodus 3:18 from World English Bible.
