And Lea said, God has given me my reward, because I gave my maid to my husband; and she called his name Issachar, which is, Reward.

And Leah said, God hath given me my hire, because I have given my maiden to my husband: and she called his name Issachar.

Leah said, “God has given me my hire, because I gave my servant to my husband.” She named him Issachar.
