'Which I Swore' in the Bible

And I will bring you in to the land which I swore to give to Abraham, to Isaac, and to Jacob, and I will give it to you for a heritage. I am LORD.

And LORD spoke to Moses, Depart, go up from here, thou and the people that thou have brought up out of the land of Egypt, to the land of which I swore to Abraham, to Isaac, and to Jacob, saying, To thy seed will I give it.
