I-Kings

And Samuel did that which the Lord spake, and came to Beth–lehem. And the elders of the town trembled at his coming, and said, Comest thou peaceably?

And David went out to meet them, and answered and said unto them, If ye be come peaceably unto me to help me, mine heart shall be knit unto you: but if ye be come to betray me to mine enemies, seeing there is no wrong in mine hands, the God of our fathers look thereon, and rebuke it.

Then the spirit came upon Amasai, who was chief of the captains, and he said, Thine are we, David, and on thy side, thou son of Jesse: peace, peace be unto thee, and peace be to thine helpers; for thy God helpeth thee. Then David received them, and made them captains of the band.

And into whatsoever house ye enter, first say, Peace be to this house.

And if the son of peace be there, your peace shall rest upon it: if not, it shall turn to you again.
