The story
- Hebrew · derived fromאֶרֶץ־גֹּשֶׁן“ʾEreṣ Gōšen”
- English todayland o' Goshen
From the place first mentioned in Genesis 45:10 as the land set aside for the Israelites when they settled in Egypt (ultimately from Hebrew אֶרֶץ־גֹּשֶׁן (“ʾEreṣ Gōšen”)). Perhaps chosen as a minced oath to replace gosh, itself a replacement for God.
