KJV
And she said unto him, My father, [if]
thou hast opened thy mouth unto the LORD, do to me according to that which
hath proceeded out of thy mouth; forasmuch as the LORD hath taken vengeance
for thee of thine enemies, [even] of the children of Ammon.
BSB
“My father,” she replied, “you have given your word to the LORD. Do to me as you have said, for the LORD has avenged you of your enemies, the Ammonites.”
