Exodus 3:12

Now Moses was pasturing the flock of Jethro his father-in-law, the priest of Midian; and he led the flock to the west side of the wilderness and came to Horeb, the mountain of God.

Then Jethro, Moses’ father-in-law, came with his sons and his wife to Moses in the wilderness where he was camped, at the mount of God.

Then they set out from Rephidim and came to the wilderness of Sinai and camped in the wilderness; and there Israel camped in front of the mountain.

And Moses said, “By this you shall know that Yahweh has sent me to do all these deeds; for this is not from my heart.

“He has not observed misfortune in Jacob; Nor has He seen trouble in Israel; Yahweh his God is with him, And the shout of a king is among them.

Then He commissioned Joshua the son of Nun and said, “Be strong and courageous, for you shall bring the sons of Israel into the land which I swore to them, and I will be with you.”

But Yahweh said to him, “Surely I will be with you, and you shall strike down Midian as one man.”

‘Then this shall be the sign for you: you will eat this year what grows of its own accord, in the second year what springs from the same, and in the third year sow, reap, plant vineyards, and eat their fruit.

“Do not be afraid of them, For I am with you to deliver you,” declares Yahweh.

“‘And I Myself will judge the nation to which they will be enslaved,’ said God, ‘and after that they will come out and serve Me in this place.’
