Then the spirit clothed Amasai, who was the leader of the 30, and he said,
“We are yours, David,
and on your side, O son of Jesse.
Peace, peace be to you,
and peace be to your helpers,
for your God helps you.”
Then David received them and made them commanders of the troops. Bible see other translations

“and he said,” This is a great example of God putting His gift of holy spirit upon someone who was not generally known as a prophet, who then gave a very powerful word of prophecy to David.

“helpers.” The Hebrew is singular, but it is a collective singular for all those who help. The Septuagint has the plural.
