🔼The name Azbuk in the Bible
The name Azbuk occurs only once in the Bible, in Nehemiah 3:16 where Azbuk is the father of a certain Nehemiah (not the famous one) who makes quite substantial repairs to the temple complex. Either this Nehemiah or his father Azbuk is an official of half the district of Beth-zur.
🔼Etymology and meaning of the name Azbuk
It's not immediately clear where this name comes from, but it's pretty sure that it consists of two elements.
The renowned scholar Gesenius takes the first element to come from the root-verb עזב (azab), meaning to leave or forsake:
The second part of the name Azbuk, according to Gesenius, comes from the verb בוק (bwq), meaning to be empty, and which comes from the verb בקק (baqaq) also meaning to be empty:
Hence, Gesenius thought the name Azbuk to mean Altogether Desolated.
Jones' Dictionary of Old Testament Proper Names passes a polite nod to Gesenius, accepts the word בוק (bwq) but then chooses for the first element of the name the fertile verb עזז ('azaz), meaning to be strong:
Hence Jones reads Strength Emptied, i.e. a strong place depopulated.
