JESHURUN jĕsh’ ə rən (יְשֻׁרוּנ׃֙, the upright one). A poetic designation for Israel (Deut 32:15; 33:5, 26; Isa 44:2). The name relates to the ideal nations, holding before the people moral and spiritual character, the object of their creation. Deuteronomy 32:15 expresses the thought of reproach for having failed the ideal; elsewhere the title is honorific.

Gesenius adopts the derivation from יָשָׁר֒, H3838, so that the word speaks of “righteous little people,” perhaps allied to the similar idea in the “book of Jasher” (Josh 10:13; 2 Sam 1:18), where Jasher appears to be a name for Israel. There is also a connection (Num 23:10) between Israel and “the righteous.”
