'Serveth' in the Bible

and Jacob serveth for Rachel seven years; and they are in his eyes as some days, because of his loving her.

And he goeth in also unto Rachel, and he also loveth Rachel more than Leah; and he serveth with him yet seven other years.

and Joseph findeth grace in his eyes and serveth him, and he appointeth him over his house, and all that he hath he hath given into his hand.

and the chief of the executioners chargeth Joseph with them, and he serveth them; and they are days in charge.
