Psalm 110:3-5

Revised Standard Version Catholic Edition

³ Your people will offer themselves freely
    on the day you lead your host
    upon the holy mountains.^[a]
From the womb of the morning
    like dew your youth^[b] will come to you.
⁴ The Lord has sworn
    and will not change his mind,
“You are a priest for ever
    after the order of Melchiz′edek.”
