Isaiah 1
1:1. Isaiah’s prophecies focus on Judah and Jerusalem. His book is called a vision, which suggests that the prophet “saw” (cf. 2:1) mentally and spiritually as well as heard what God communicated to him. This word “vision” also introduces the prophecies of Obadiah, Micah, and Nahum.
The obedient (v. 19) would eat the best from the land, that is, they would have bountiful crops as promised in the Mosaic Covenant (Deut. 28:3–6, 11). By contrast, those who refused to turn to God (rebels; cf. Isa. 1:23, 28) would be defeated by enemies (devoured by the sword, v. 20; Deut. 28:45–57). This was certain for the … LORD has spoken (cf. Isa. 40:5; 58:14).
1:21. The contrast between the original condition of Jerusalem under David and the early years of Solomon’s reign with the condition of the people in Isaiah’s day is detailed. At one time Jerusalem was considered faithful like a devoted wife. Now, however, the city was a harlot. The imagery of prostitution is common in the prophetic books (esp. Jer. and Hosea). This figure is based on the fact that in marriage, as in the relationship between God and Israel, a covenant was made. When a person becomes a prostitute he or she mars the marriage covenant. In the same way when a person left the true God for idols he marred his covenant with the Lord.
Their silver and wine, which used to be valuable, had become worthless: dross metal and watered-down wine. Dross is the residue left in the smelting process after pure silver is removed. Like worthless dross, the nation would be “thrown away.” The people would be exiled if they would not repent and turn to the Lord.
The rebellious rulers in the city were leading the people into ruin by theft, bribery, and injustice to the helpless (cf. comments on v. 17). The fatherless and widows could not even get hearings because they had no money for bribing the rulers. This situation was especially abhorrent to God because His covenant people were bound to Him and therefore to each other. But now they had no concern for each other’s property and needs.
God’s lawsuit ended with His pronouncing judgment on the guilty nation. In this chapter God is pictured not only as one of the parties in the litigation but also as the Judge who will decide what will happen to the guilty party. Those who were obstinate, refusing to repent, would be judged, but the repentant would be redeemed.
