'Served' in the Bible

These men and their sons served from the Kohathites: Heman the singer, the son of Joel, the son of Samuel [the great prophet and judge],

When David was told how the men were treated, he sent messengers to meet them, for they were very humiliated and ashamed [to return]. So the king said, “Stay in Jericho until your beards grow [back], and then return.”

This is the list of the sons (descendants) of Israel, the heads of fathers’ households, the commanders of thousands and of hundreds, and their officers who served the king in all matters of the divisions which came in and went out month by month throughout the year, each division numbering 24,000:

David assembled at Jerusalem all the leaders (officials) of Israel, the leaders of the tribes, and the commanders of the divisions that served the king, and the commanders of thousands, and the commanders of hundreds, and the overseers of all the property and livestock of the king and his sons, with the palace officers and the mighty men, and all the brave warriors.
