'Serve' in the Bible

Then David ordered [that] none except the Levites should carry the ark of God, for Yahweh had chosen them to carry the ark of Yahweh and to serve him forever.

The sons of Amram: Aaron and Moses. And Aaron was set apart to consecrate the most holy things. He and his sons [were] to burn offerings forever before Yahweh to serve him and to bless in his name forever.

And they shall keep the responsibility of the tent of assembly, the responsibility of the sanctified objects, and the responsibility of the sons of Aaron, their brothers, to serve the house of Yahweh.

These working groups of gatekeepers, corresponding to the chief men, had responsibilities like their brothers to serve in the house of Yahweh.

And as for the number of the {Israelites}, the heads of {families}, the commanders of thousands and hundreds, and their officials who serve the king in all matters of the working groups that came and went, month by month, throughout all the months of the year, each working group: twenty-four thousand.

"And you, Solomon my son, know the God of your father and serve him with a whole heart and a willing mind, for Yahweh searches all hearts and understands every plan and [all] thoughts. If you seek him, he will be found by you, but if you abandon him, he will reject you forever.
