Exodus 3:18 AMP

[18] The elders [of the tribes] will listen and pay attention to what you say; and you, with the elders of Israel, shall go to the king of Egypt and you shall say to him, ‘The LORD, the God of the Hebrews, has met with us; so now, please, [we ask and plead with you,] let us go on a three days’ journey into the wilderness, so that we may sacrifice to the LORD our God.’
