Charles Ellicott Commentary Nehemiah 9:6

"Thou art Jehovah, even thou alone; thou hast made heaven, the heaven of heavens, with all their host, the earth and all things that are thereon, the seas and all that is in them, and thou preservest them all; and the host of heaven worshippeth thee." — Nehemiah 9:6 (ASV)

Preservest them all. —In this comprehensiveness reproduced only in Hebrews 1:3.

The host of heaven. —First the stars, but here the angels (Psalms 103:21).
