Charles Ellicott Commentary Deuteronomy 30:4

"If [any of] thine outcasts be in the uttermost parts of heaven, from thence will Jehovah thy God gather thee, and from thence will he fetch thee:" — Deuteronomy 30:4 (ASV)

If any of thine be driven out. —In the Septuagint, "If your dispersion is."

Unto the outmost parts of heaven. —The Septuagint version of these words is traceable in Matthew 24:31, From the one end of heaven to the other.
