And he saw that there was no man, and wondered that there was no intercessor: therefore his arm brought salvation unto him; and his righteousness, it sustained him. For he put on righteousness as a breastplate, and an helmet of salvation upon his head; and he put on the garments of vengeance for clothing, and was clad with zeal as a cloke. According to their deeds, accordingly he will repay, fury to his adversaries, recompence to his enemies; to the islands he will repay recompence. So shall they fear the name of the LORD from the west, and his glory from the rising of the sun. When the enemy shall come in like a flood, the Spirit of the LORD shall lift up a standard against him. And the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the LORD. As for me, this is my covenant with them, saith the LORD; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed’s seed, saith the LORD, from henceforth and for ever.
When the LORD looked upon the earth, He is grieved that there is no justice. He marvels that there is no intercessor or mediator capable of handling the situation, so He steps in and does it Himself. His own strength brings Him victory and His own righteousness upholds Him. He dons the armor and moves out against His foes in righteousness, salvation, vengeance, zeal, and fury. He gives the Gentiles exactly what they deserve, so that, at last, all the people from east to west are forced to acknowledge that He is Lord, for the Messiah comes in like a flood, driven by the breath of Jehovah. He will come as Redeemer to the godly remnant in Zion. Then God will make a new covenant with the house of Israel.
