Midras Amos 3:13: Aggadat Bereshit

[2] Another interpretation: "And she vowed a vow and said..." (1 Samuel 1:11). This is in reference to "And the Lord God, Lord is remembered" (Hosea 12:6) [tzevaot - Armies, war etc.] the Hosts , Lord God Hosts [edit. YHVH elohiy Tzevaot]" (Amos 3:13), indicating that God brings about our glory both in the heavenly hosts and the earthly hosts. How does He bring about our glory in the earthly hosts? As it says, "He who calls the waters of the sea and pours them out upon the face of the earth" (Amos 9:6). And how does He bring about our glory in the heavenly hosts? As it says, "The stars in their courses fought against Sisera" (Judges 5:20). Hannah said [to God], "If you grant me children from the armies below, as you have promised, then I will be blessed among all nations, and there shall be no barrenness in me" (Deuteronomy 7:14). But if it is from the armies above that I seek, then make me a sign that I may be established as they are, with life and continuity. Therefore it is said, "The Lord of hosts."
