formed ... from ... womb - (So Isa 44:24; Isa 49:1, Isa 49:5). The sense is similar to that in Isa 1:2, “I have nourished and brought up children.”
Jesurun - A diminutive term of endearment applied to Israel. The full title of affection was Israelun; contracted it became Jeshurun, with an allusion to the Hebrew root, jashar, “upright,” “perfect” (see on Isa 42:19, note on “He that is perfect”) [Gesenius], (Deu 32:15).
