Charles Spurgeon Commentary Nehemiah 1:7-9

"we have dealt very corruptly against thee, and have not kept the commandments, nor the statutes, nor the ordinances, which thou commandedst thy servant Moses. Remember, I beseech thee, the word that thou commandedst thy servant Moses, saying, If ye trespass, I will scatter you abroad among the peoples: but if ye return unto me, and keep my commandments and do them, though your outcasts were in the uttermost part of the heavens, yet will I gather them from thence, and will bring them unto the place that I have chosen, to cause my name to dwell there." — Nehemiah 1:7-9 (ASV)

Remember, I beseech thee, the word that thou commandedst thy servant Moses, saying, If ye transgress, I will scatter you abroad among the nations: But if ye turn unto me, and keep my commandments, and do them; though there were of you cast out unto the uttermost part of the heaven, yet will I gather them from thence, and will bring them unto the place that I have chosen to set my name there.
