The singers played instruments and sang for worship at the temple (1 Chronicles 25:1–31; Psalms 73–83). The gatekeepers managed the temple gates and storehouses (1 Chronicles 9:26–27; 2 Chronicles 23:19; Nehemiah 12:25).
Asaph was one of the three Levites King David appointed to lead music at the temple (1 Chronicles 16:5, 7). He wrote a collection of psalms (Psalms 50, 73–83). His family continued his work (1 Chronicles 25:1–7).
