A poetical name for the people of Israel, used in token of affection, meaning, “the dear upright people” (Deut. 32:15; 33:5, 26; Isa. 44:2).
Jeshurun
Jeshurun is a poetic name for Israel, and each time it appears it is said with tenderness. Moses uses it when he sings of the people who grew comfortable: “Jeshurun waxed fat, and kicked,” and forsook the God who made him. Yet Moses also blesses them, saying there is none like unto the God of Jeshurun. Isaiah, centuries on, hears the LORD speak the name again: “Fear not, O Jacob, my servant; and thou, Jesurun, whom I have chosen.” The name speaks of a chosen people, who sometimes forgot that and were still loved.

(supremely happy), and once by mistake in Authorized Version JESURUN, (Isaiah 44:2) a symbolical name for Israel in (32:15; 33:5,26; Isaiah 44:2) It is most probably derived from a root signifying "to be blessed." With the intensive termination Jeshurun would then denote Israel as supremely happy or prosperous, and to this signification the context in (32:15) points.
