Jehobah ya zaɓi Lawiyawa su yi masa hidima maimakon duka ’ya’yan fari na Isra’ila su riƙa yin haka (L.Ƙi 3:​11-13; it-2-E 683 ¶3)

Lawiyawan sun yi wasu ayyuka masu muhimmanci (L.Ƙi 3:​25, 26, 31, 36, 37; it-2-E 241)

Lawiyawan sun yi aiki tuƙuru a lokacin da suke tsakanin shekara 30 da 50 (L.Ƙi 4:​46-48; it-2-E 241)

Mazan da suka fito daga zuriyar Haruna ne suke yin hidimar firist. Sauran Lawiyawan kuma suna taimaka musu. Haka ma a ikilisiyar Kirista, wasu maza suna yin ayyuka masu muhimmanci, wasu kuma suna taimaka musu da yin wasu ayyuka a ikilisiya.
