Exodus 6:5 WEB

³  and I appeared to Abraham, to Isaac, and to Jacob, as God Almighty; but by my name Yahweh I was not known to them.

⁴  I have also established my covenant with them, to give them the land of Canaan, the land of their travels, in which they lived as aliens.

⁵  Moreover I have heard the groaning of the children of Israel, whom the Egyptians keep in bondage, and I have remembered my covenant.

⁶  Therefore tell the children of Israel, 'I am Yahweh, and I will bring you out from under the burdens of the Egyptians, and I will rid you out of their bondage, and I will redeem you with an outstretched arm, and with great judgments:

⁷  and I will take you to me for a people, and I will be to you a God; and you shall know that I am Yahweh your God, who brings you out from under the burdens of the Egyptians.
