A personal name meaning 'my brother is good,' from ach (brother) and tov (good). Borne by several priests including the father of Zadok.
Achitub appears as a priestly name across generations: father of Zadok (2 Samuel 8:17) who became the faithful high priest under Solomon. The name 'my brother is good' reflects covenant faithfulness. Jesus, the ultimate High Priest, is not ashamed to call believers brothers (Hebrews 2:11).
