The sentiment is common in the Bible, that kings and nations are in the hand of God; and that he overrules and directs their actions for the accomplishment of his own purposes, and especially to protect, defend, and deliver his people (see the note at Isaiah 10:5; compare Isaiah 47:6).

“Jacob: Isa 41:8, Isa 41:9, Isa 43:3, Isa 43:4, Isa 43:14, Isa 44:1; Exo 19:5, Exo 19:6; Jer 50:17-20; Mat 24:22; Mar 13:20; Rom 9:6, Rom 11:7 I have even: Isa 45:1, Isa 44:28 though: Act 17:23; Gal 4:8, Gal 4:9; Eph 2:12; Th1 4:5 Isaiah 45:5”

“A second and third object are introduced by a second and third למען. "For the sake of my servant Jacob, and Israel my chosen, I called thee hither by name, surnamed thee when thou knewest me not. I Jehovah, and there is none else, beside me no God: I equipped thee when thou knewest me not; that they may know from the rising of the sun, and its going down, that there is none without me: I Jehovah, and there is none else, former of the light, and creator of the darkness; founder of peace, and creator of evil: I Jehovah am He who worketh all this."
