The Lord says to my lord:^[a]

“Sit at my right hand
    until I make your enemies
    a footstool for your feet.”

² The Lord will extend your mighty scepter from Zion, saying,
    “Rule in the midst of your enemies!”
³ Your troops will be willing
    on your day of battle.
Arrayed in holy splendor,
    your young men will come to you
    like dew from the morning’s womb.^[b]

⁴ The Lord has sworn
    and will not change his mind:
“You are a priest forever,
    in the order of Melchizedek.”

⁵ The Lord is at your right hand^[c];
    he will crush kings on the day of his wrath.
⁶ He will judge the nations, heaping up the dead
    and crushing the rulers of the whole earth.
⁷ He will drink from a brook along the way,^[d]
    and so he will lift his head high. Psalm 110
