🔼The name Jaziz in the Bible
The name Jaziz occurs only one time in the Bible. In 1 Chronicles 27:31 Jaziz the Hagrite is mentioned as the manager of David's flocks (not counting the donkeys, which were taken care of by Jehdeiah, or the camels which were kept by Obil, or the cattle which were looked after by Shaphat and Shitrai).
🔼Etymology of the name Jaziz
The graceful name Jaziz comes from the root group זוז (zwz I & II):
The name Jaziz is formed from the noun זיז, meaning either moving things or abundance, prefixed with the letter yod. This activates the root and would mean: he will ziz.
For a meaning of the name Jaziz, NOBSE Study Bible Name List takes a wild leap of liberality and reads Shining (and this may have to do with an Aramaic root of similar form, which means just that). Jones' Dictionary of Old Testament Proper Names takes our name from zwz II and suggests the more proper He Will Bring Abundance.
