A desperate plea for restoration and salvation echoes multiple times throughout the prayer. A person deep in prayer naturally repeats their cries to strengthen their request and express the profound urgency of their need [רד״ק].
As the prayer intensifies, God is addressed specifically as the ruler over the heavenly armies and angels. This marks a shift from earlier moments where He is addressed simply as God, and it carries a deep spiritual argument. The primary purpose of angelic beings is to serve as a channel, bringing divine abundance from the upper spiritual realms down to this world and to the Israelites. Without the Israelites to receive this blessing, the existence of the angels loses its meaning. Therefore, the plea asks God to restore His people not only for their own survival but to validate and sustain the very purpose of the heavenly hosts [אלשיך].
Ultimately, this passionate cry for rescue is focused on a specific historical threat, begging for deliverance from the oppression of the Greeks [רש״י].
