Exodus 6:4

וגם הקמתי את בריתי וגו׳ Then, ALSO, when I appeared unto them by the name of God Almighty I ESTABLISHED and set up MY COVENANT between Myself and them לתת להם את ארץ כנען TO GIVE THEM THE LAND OF CANAAN — Of Abraham it is stated in the chapter that contains the commandment of the Circumcision, (Genesis 17:1, and 17:8) “[The Lord appeared to Abraham and said unto him], I am God Almighty etc., and I will give to thee and to thy seed after thee the land of thy sojourning”. Of Isaac it is stated, (Genesis 26:3) “[The Lord appeared unto him and said], For unto thee and unto thy seed I will give all these countries, and I will establish the oath which I sware unto Abraham, thy father”, and that oath here referred to which I sware to Abraham I uttered by the name of God Almighty. Of Jacob it is stated, (Genesis 35:9, 11, 12) “[And God appeared unto Jacob … and God said unto him], I am God Almighty; be fruitful and multiply, … the land which I gave [Abraham and Isaac to thee I will give it] etc.” So you see that I made certain vows to them and I have not yet fulfilled them.

וְגַ֨ם הֲקִמֹ֤תִי אֶת־בְּרִיתִי֙ אִתָּ֔ם לָתֵ֥ת לָהֶ֖ם אֶת־אֶ֣רֶץ כְּנָ֑עַן אֵ֛ת אֶ֥רֶץ מְגֻרֵיהֶ֖ם אֲשֶׁר־גָּ֥רוּ בָֽהּ׃

And I have also established my covenant with them, to give them the land of Kena῾an, the land of their sojournings, in which they sojourned.
