Jamieson, Fausset and Brown on Isaiah 40:26

26. bringeth out ... host--image from a general reviewing his army: He is Lord of Sabaoth, the heavenly hosts (Job 38:32).

calleth ... by names--numerous as the stars are. God knows each in all its distinguishing characteristics--a sense which "name" often bears in Scripture; so in Ge 2:19, 20, Adam, as God's vicegerent, called the beasts by name, that is, characterized them by their several qualities, which, indeed, He has imparted.

by the greatness ... faileth--rather, "by reason of abundance of (their inner essential) force and firmness of strength, not one of them is driven astray"; referring to the sufficiency of the physical forces with which He has endowed the heavenly bodies, to prevent all disorder in their motions [Horsley]. In English Version the sense is, "He has endowed them with their peculiar attributes ('names') by the greatness of His might," and the power of His strength (the better rendering, instead of, "for that He is strong").
