5 Like he does the flying birds, so Yahveh of armies will protect Jerusalem; he will protect and deliver it; he will pass over and rescue it. 6 Turn back to him from whom the sons of Israel have made deep rebellion. 7 Because on that day, each of you will reject his silver idols and his gold idols which your hands have made sinfully for yourselves. 8 And Assyria will fall by a non-human sword, and a non-human sword will devour him; and he will flee from that sword, and his young men will be enslaved. 9 And his rock will pass over because of terror, and his officers will be terrified of a flag,” – a declaration of Yahveh, who has a fire in Zion and has a furnace in Jerusalem.
a non-human sword
Isaiah encourages his people to trust in Yahveh of armies, but tells them that this time their protection is not going to come from an army. It will be a non-human sword that causes this Assyrian menace to fall. Some of the armies God controls are angelic armies. He lacks no resource when it comes to protecting his people.
LORD, thank you for your love and protection. Thank you for all the ways you take care of those who trust in you.
