'Exercised' in the Bible

And Nadab and Abihu died before Jehovah when they offered strange fire before Jehovah in the wilderness of Sinai, and they had no sons; and Eleazar and Ithamar exercised the priesthood in the presence of Aaron their father.

(And the children of Israel took their journey from Beeroth-Bene-Jaakan to Moserah: there Aaron died, and there he was buried; and Eleazar his son exercised the priesthood in his stead.

and Johanan begot Azariah (he is it that exercised the priesthood in the house that Solomon built in Jerusalem);

And Nadab and Abihu died before their father, and had no children; and Eleazar and Ithamar exercised the priesthood.

and hath not oppressed any; he hath restored to the debtor his pledge, hath not exercised robbery, hath given his bread to the hungry, and covered the naked with a garment;

hath oppressed the poor and needy, exercised robbery, hath not restored the pledge, and hath lifted up his eyes to the idols, committed abomination,

and hath not oppressed any, nor withholden the pledge, neither hath exercised robbery; he hath given his bread to the hungry, and covered the naked with a garment;

As for his father, because he practised oppression, exercised robbery upon his brother, and did what was not good among his people, behold, he shall die in his iniquity.
