Charles Ellicott Commentary Exodus 6:7

"and I will take you to me for a people, and I will be to you a God; and ye shall know that I am Jehovah your God, who bringeth you out from under the burdens of the Egyptians." — Exodus 6:7 (ASV)

I will take you to me for a people. —Compare to Exodus 19:5-6; Deuteronomy 7:6.

The selection of Israel as a peculiar people did not involve the abandonment of all other nations, as we see by the instances of Balaam, Ruth, Job, Nebuchadnezzar, Darius the Mede, Cyrus, and others. God always continued to govern all the nations upon the earth (Psalms 67:4); and in every nation those that feared him and worked righteousness were accepted with him (Acts 10:35). The centurion of the Gospels (Matthew 8:5–13; Luke 7:2–10) and Cornelius in the Acts (Acts 10:1–33) carry the same principle into Gospel times.

I will be to you a God. —See Genesis 17:8.
