Problem: According to this verse, Caleb’s father was Hezron. But verse 50 says it was Hur, and Joshua 14:6 lists it as Jephunneh.
Solution: Several solutions are possible. Some scholars believe there may have been two or three Calebs. Others note that the word “son” may mean grandson of even great-grandson. Hence, these men could refer to Caleb’s father, grandfather, and great-grandfather. Also, some think that 1 Chronicles 2:50 may not affirm that Caleb is the son of Hur. By placing a period after Caleb (see nasb), the phrase “these are the descendants of Caleb” refers to the preceding verse. If so, Hur would not be the father of Caleb.
