'Served' in the Bible

"Long ago your ancestors lived beyond the Euphrates River, including Terah, father of both Abraham and Nahor, where they served other gods. Then I took your ancestor Abraham from the other side of the Euphrates River and led him through the entire land of Canaan. I multiplied his descendants, and gave him his son Isaac.

"Now you must fear the LORD and serve him in faithfulness and truth. Throw away the gods that your ancestors served beyond the Euphrates River and in Egypt. Instead, serve the LORD.

If you think it's the wrong thing for you to serve the LORD, then choose for yourselves today whom you will serve the gods whom your ancestors served on the other side of the Euphrates River, or the gods of the Amorites in whose territories you are living. But as for me and my household, we will serve the LORD."

Israel served the LORD for the entire lifetimes of Joshua and of the officials who outlived Joshua, that is, the ones who had personally known everything that the LORD had done for Israel.
