Ashur was the son of Hezron, who was the son of Pharez, who was the son of Judah and Tamar. In short, Ashur was the great grandson of Judah. In the Bible, we find the the following reference to Ashur:
“And after that Hezron was dead in Calebephratah, then Abiah Hezron’s wife bare him Ashur the father of Tekoa.” – 1 Chronicles 2:24
The name Ashur is also an ethnonym, which is a name that describes someone’s skin color. If we check the Strong’s Concordance on Bible Hub, it brings us to Strong’s #806 (Ashchuwr).
If we scroll down the page to Strong’s Exhaustive concordance, it gives the root word of Ashur as “shacar” (Strong’s #7835), which is defined as follows:
“A primitive root (identical with shachar through the idea of the duskiness of early dawn); to be dim or dark (in color) — be black.”
Names in ancient times often represented physical features or unique characteristics that an individual displayed. This name could indicate Ashur was dark-skinned.
