Charles Ellicott Commentary Isaiah 60:10

"And foreigners shall build up thy walls, and their kings shall minister unto thee: for in my wrath I smote thee, but in my favor have I had mercy on thee." — Isaiah 60:10 (ASV)

The sons of strangers shall build ... —Either as willing proselytes or as being brought into subjection. (Compare to Zechariah 6:15.) To build the temples or palaces of conquerors was, as in the case of the Egyptian and Babylonian bondage, the almost inevitable lot of the conquered.
