¹ sn This refers to Shear Jashub (7:3) and Maher Shalal Hash Baz (8:1, 3).

² sn The twofold appearance of the statement “a remnant will come back” (שְׁאָר יָשׁוּב, sheʾar yashuv) in vv. 21-22 echoes and probably plays off the name of Isaiah’s son Shear Jashub (see 7:3). In its original context the name was meant to encourage Ahaz (see the note at 7:3), but here it has taken on new dimensions. In light of Ahaz’s failure and the judgment it brings down on the land, the name Shear Jashub now foreshadows the destiny of the nation. According to vv. 21-22, there is good news and bad news. The good news is that a remnant of God’s people will return; the bad news is that only a remnant will be preserved and come back. Like the name Immanuel, this name foreshadows both judgment (see the notes at 7:25 and 8:8) and ultimate restoration (see the note at 8:10).

² tn Or “signs and portents” (NAB, NRSV). The names of all three individuals has symbolic value. Isaiah’s name (which meant “the Lord delivers”) was a reminder that the Lord was the nation’s only source of protection; Shear Jashub’s name was meant, at least originally, to encourage Ahaz (see the note at 7:3), and Maher Shalal Hash Baz’s name was a guarantee that God would defeat Israel and Syria (see the note at 8:4). The word מוֹפֶת (mofet, “portent”) can often refer to some miraculous event, but in 20:3 it is used, along with its synonym אוֹת (ʾot, “sign”) of Isaiah’s walking around half-naked as an object lesson of what would soon happen to the Egyptians.
