Orthodox Jewish Bible

⁵⁴ And Dovid took the rosh of the Pelishti, and brought it to Yerushalayim; but he put his kelim (weapons) in his ohel.

⁵⁵ And when Sha’ul saw Dovid go forth to meet the Pelishti, he said unto Avner, the sar hatzavah, Avner, whose ben is this na’ar? And Avner said, As thy nefesh liveth, O Melech, I cannot tell.

⁵⁶ And the Melech said, Inquire thou whose ben this elem (young man) is.
