5. Lord God—Jehovah, a name implying His immutable constancy to His promises. From the Hebrew root, meaning "existence." "He that is, was, and is to be," always the same (Heb 13:8; Re 1:4, 8; compare Ex 3:14, 15; 6:3). As He was unchangeable in His favor to Jacob, so will He be to His believing posterity.
of hosts—which Israel foolishly worshipped. Jehovah has all the hosts (saba) or powers of heaven and earth at His command, so that He is as all-powerful, as He is faithful, to fulfil His promises (Ps 135:6; Am 5:27).
memorial—the name expressive of the character in which God was ever to be remembered (Ps 135:13).
