Judges 10:4

“And he had thirty sons that rode upon thirty ass colts, etc.] Which to ride on in those times was reckoned honourable, and on which judges rode in their circuit, (<070510>Judges 5:10) and such might be these sons of Jair, who were appointed under him to ride about, and do justice in the several parts of the country, as Samuel’s sons were judges under him, (<090801>1 Samuel 8:1), and they had thirty cities, which are called Havothjair unto this day, which are in the land of Gilead; or the villages of Jair. There were some of this name that belonged to Jair, a son of Manasseh, in the times of Moses, (<043241>Numbers 32:41) and these may be the same, at least some of them; for they were but…”

“he had thirty sons that rode on thirty ass colts--This is a characteristic trait of Eastern manners in those early times; and the grant of a village to each of his thirty sons was a striking proof of his extensive possessions.

There are instances, in this country, of men having as many children by two successive wives.”

“And he had thirty sons - They were itinerant judges, who rode from place to place, as their father's deputies to administer justice. Havoth - jair - These villages were called so before this time from another Jair, but the old name was revived and confirmed upon this occasion. Judges 10:6”

“rode: Jdg 5:10, Jdg 12:14 called: Num 32:41; Deu 3:14 Havothjair: or, the villages of Jair Judges 10:6”
