But if ye return unto me, and keep my commandments, and do
them
Return by repentance, and, as a proof of the genuineness of it, yield obedience to the commands of God, and continue therein:
though there were of you cast out unto the uttermost part of the
heaven;
that is, the uttermost parts of the earth, the most distant regions; so called, because at the extreme parts of the horizon, according to our apprehension, the heavens and earth touch each other; so that what is the uttermost part of the one is supposed to be of the other:
yet will I gather them from thence and will bring them unto the place
that I have chosen to set my name there;
that is to Jerusalem where the temple was built, and his name was called upon.
