Domine rex omnipotens

Antonius Gallus's Domine rex omnipotens is a motet for SATTB choir, sung in Latin. The text is a prayer for divine intervention and mercy in times of persecution. It begins with a declaration of God's almighty power as creator of heaven and earth, and acknowledges His supreme dominion. The singer (likely representing Queen Esther in the context of the Book of Esther) asserts that their actions are not motivated by pride or ambition, but by a fear of transferring God's honour to a mere mortal, refusing to worship the proud Haman. The plea continues, asking God, as the God of Abraham, to have mercy on His people, who are threatened by enemies seeking to destroy their inheritance. The prayer implores God to hear their supplication, favour His portion, and turn their sorrow into joy, so that they may live to praise His name.
