Jesaja 48:21

This third portion of the trilogy (Isa 46:1-13, Isa 47:1-15, 48) stands in the same relation to Isa 47:1-15, as Isa 46:3. to Isa 46:1-2. The prophecy is addressed to the great body of the captives. "Hear ye this, O house of Jacob, who are called by the name of Israel, and have flowed out of the waters of Judah, who swear by the name of Jehovah, and extol the God of Israel, not in truth and not in righteousness! For they call themselves of the holy city, and stay themselves upon the God of Israel, Jehovah of hosts His name." The summons to hear is based upon the Israelitish nationality of those who are summoned, to which they still cling, and upon the relation in which they place themselves to the God of Israel. This gives to Jehovah the right to turn to them, and imposes upon them the duty to hearken to Him. The blame, inserted by the way, points at the same time to the reason for the address which follows, and to the form which it necessarily assumes. "The house of Jacob" is not all Israel, as the following words clearly show, but, as in Isa 46:3, the house of Judah, which shared in the honourable name of Israel, but have flowed out of the waters, i.e., the source of Judah. The summons, therefore, is addressed to the Judaean exiles in Babylon, and that inasmuch as they swear by the name of Jehovah, and remember the God of Israel with praise (hizkı̄r b' as in Psa 20:8), though not in truth and not in righteousness (Kg1 3:6; Zac 8:8), i.e., without their state of mind (cf., Isa 38:3; Jer 32:41) or mode of action corresponding to their confession, so as to prove that it was sincerely and seriously meant. The praise bestowed upon the persons summoned, which is somewhat spoiled by this, is explained in Isa 48:2; they call themselves after the holy city (this title is applie…

God, having in the foregoing chapter reckoned with the Babylonians, and shown them their sins and the desolation that was coming upon them for their sins, to show that he hates sin wherever he finds it and will not connive at it in his own people, comes, in this chapter, to show the house of Jacob their sins, but, withal, the mercy God had in store for them notwithstanding; and he therefore sets their sins in order before them, that by their repentance and reformation they might be prepared for that mercy. I. He charges them with hypocrisy in that which is good and obstinacy in that which is evil, especially in their idolatry, notwithstanding the many convincing proofs God had given them that he is God alone, (Isa 48:1-8). II. He assures them that their deliverance would be wrought purely for the sake of God's own name and not for any merit of theirs (Isa 48:9-11). III. He encourages them to depend purely upon God's power and promise for this deliverance (Isa 48:12-15). IV. He shows them that, as it was by their own sin that they brought themselves into captivity, so it would be only by the grace of God that they would obtain the necessary preparatives for their enlargement (Isa 48:16-19). V. He proclaims their release, yet with a proviso that the wicked shall have no benefit by it (Isa 48:20-22).

48:21 not thirsty . . . rock . . . water gushed: These reminders of God’s provision in the Exodus provide a fitting summary of what he would do to rescue Israel from captivity in Babylon (see Num 20:11).
