A poetical name for Israel. It is possibly derived from the Hebrew root meaning “upright.” According to many scholars, it is a diminutive of Israel. A diminutive is a version of a word or an ending added to a word to make it smaller, such as "little Israel."
The name Jeshurun is used in Deuteronomy 32:15 and 33:5, 26. In the Greek translation of the Old Testament, the word is not translated as a proper name but as an adjective, “beloved.” In Isaiah 44:2, Jacob is described as “Jeshurun, whom I have chosen.” This links the name with the idea of election or choosing.
In Deuteronomy 33:5 Israel is reminded that “the LORD became king in Jeshurun." Verse 26 says, “There is none like the God of Jeshurun." If we follow the Septuagint (Greek translation of the Old Testament), there is a link with the term “beloved” used of Christ in Matthew 3:17, Mark 1:11, and Ephesians 1:6, and of the church in Colossians 3:12, 1 Thessalonians 1:4, 2 Thessalonians 2:13, and Jude 1:1.
