🔼The name Chelubai in the Bible
The name Chelubai occurs only once in the Bible. In 1 Chronicles 2:9 he is mentioned as a son of Hezron of Judah. This Hezron is also the father of a man named Caleb, and Caleb isn't mentioned in 1 Chronicles 2:9, so scholars assume that the name Caleb (כלב) is a shortened version of the name Chelubai (כלובי).
🔼Etymology of the name Chelubai
The name Chelubai is the word כלוב (kelub), meaning cage or basket, extended with the letter י (yod):
The letter י (yod) upon which our name ends, may either turn the noun into a possessive form: my basket; or it turns the noun into an adjective: basket-like; or it is a remnant of יה (Yah) = יהו (Yahu) = יו (Yu), which in turn are abbreviated forms of the Tetragrammaton; the name of the Lord: YHWH.
For a meaning of the name Chelubai, Jones' Dictionary of Old Testament Proper Names interprets the source of the word כלוב (kelub) to be a verb that means to interweave or bind, and the final י as a remnant of YHWH, and reads Binding Together Of The Lord.
