sn The text mentions David’s father Jesse, instead of the great king himself. Perhaps this is done for rhetorical reasons to suggest that a new David, not just another disappointing Davidic descendant, will arise. Other prophets call the coming ideal Davidic king “David” or picture him as the second coming of David, as it were. See Jer 30:9; Ezek 34:23–24; 37:24–25; Hos 3:5; and Mic 5:2 (as well as the note there).

tc The Hebrew text has יִפְרֶה (yifreh, “will bear fruit,” from פָּרָה, parah), but the ancient versions, as well as the parallelism suggest that יִפְרַח (yifrakh, “will sprout”, from פָּרַח, parakh) is the better reading here. See J. N. Oswalt, Isaiah (NICOT), 1:276, n. 2.
