The LXX renders this passage, “Thus says the Lord, with a mighty hand they have turned away from the paths of this people, saying, 'Let them not say this is burdensome,' for whatever this people deems as burdensome should not instill fear or dismay in you." You should sanctify the Lord of Hosts, for He will be your fear; those who put their trust in Him will find their sanctification and will not stumble as a stone of offense or a rock of despair. The house of Jacob will be as a net and a valley to those who sit in Jerusalem; consequently, many will be weakened, fall, be broken, draw near, and become ensnared.
Initially, it is important to reflect on the Hebrew text. The Lord has said to me, He who has enlightened and guided me with His strong hand so that I avoid the paths and errors of this people. He has instructed me: "Do not fear the conspiracy of the two kings; rather, remember that all this people accuses me of conspiracy, as Symmachus suggests, interpreting it as a rebellion against me." But you, O prophet, and your companions, are not to be afraid of the people's deceit, but rather fear the Lord and let Him be your reverence. For the beginning of wisdom is the fear of the Lord, as stated in Proverbs 1:7 and Psalm 110:9. To the faithful, He will be their sanctification, but to the disbelieving—specifically the two houses of Judah and Israel—He will be a stumbling stone and a rock of offense. He will certainly be a snare and a fall for the inhabitants of Jerusalem, leading many to stumble, fall, and be caught, entangled in their sinful bonds and led into captivity.
The two houses of the Nazarenes—the families of Shammai and Hillel—represent those who accept Christ while still adhering to the Old Testament law. These houses produced the scribes and Pharisees, whose lineage eventually led to Akiba, regarded as the teacher of the proselyte Akilah, and subsequently to Meir, followed by Johanan, Eliezer, Telfon, and Joseph of Galilee. Shammai and Hillel arose in Judah shortly before Christ’s birth. The names carry meanings of devastation and uncleanness, indicating how their traditions and secondary interpretations led to the corruption of the Law’s commandments. They represent the two houses that rejected the Savior, who ultimately became their downfall and trial.
According to the LXX, the people resisted God’s will with a strong hand, declaring His commands to be burdensome—echoing the sentiment found in the Gospel: "This saying is hard; who can accept it?" (John 6:60). Thus, they are called to heed the Lord and to fear Him alone. By placing their hope in Him, He will become their sanctification, and they will not trip as against a rock of offense or a stone of disgrace. The apostle cites this notion, noting that Christ was both a stumbling block to the Jews and foolishness to the Gentiles (1 Corinthians 1:23). Furthermore, Israel pursued a law of righteousness yet failed to achieve it because it stemmed from works rather than faith; they encountered the stone of stumbling, as it is written: "Behold, I lay in Zion a stone of stumbling and a rock of offense, and he who believes in Him will not be put to shame" (Romans 9:31-33). Thus, those who did not embrace Immanuel, but rather regarded Him as a stumbling block and a rock of offense, will be broken and taken captive. The statement that "the house of Jacob shall be a net and a valley for those who sit in Jerusalem" signifies that they will not dwell upon the heights of Scripture, but will constantly dwell in humble matters, adding sin to sin while becoming ensnared in vices.
