Imamat 24:10

A Case of Blaspheming the Name

24:10 Now ¹  an Israelite woman’s son whose father was an Egyptian went out among the Israelites, and the Israelite woman’s son and an Israelite man ²  had a fight in the camp.

[24:10]  ¹ tn Heb “And.”

[24:10]  ² tn Heb “the Israelite man,” but Smr has no article, and the point is that there was a conflict between the man of mixed background and a man of full Israelite descent.
