"You are righteous, O Lord, etc." Solomon said (Proverbs 8:8-9), "In righteousness, all the words of my mouth are just; none of them is crooked or perverse. All of them are clear to the perceptive, etc." What is meant by "In righteousness, all the words of my mouth"? Everything that the Lord has spoken from His mouth in righteousness, they are righteous and upright. Therefore it is said, "You are righteous, O Lord, and Your judgments are upright."
Just as You are righteous, so are Your judgments righteous and upright. And it is also said (Deuteronomy 4:7), "For what great nation is there that has God so close to them, etc." And so the Assembly of Israel said (Nehemiah 9:13), "And You descended upon Mount Sinai and spoke with them from heaven, and gave them just ordinances, etc." Therefore it is said, "You are righteous, O Lord, etc." "You have commanded righteousness in Your testimonies."
What is meant by "You have commanded righteousness"? The Lord acted righteously with Israel by giving them the Torah. And it is also said (Deuteronomy 6:24), "And the Lord commanded us to do all these statutes, to fear the Lord our God, etc." What is written after it? "And it will be righteousness for us if we are careful to do all these commandments before the Lord our God, etc." Therefore it is said, "You have commanded righteousness in Your testimonies."
"What is faith? Great faith is the Torah, in which the Lord created his world and swore by it, as it is said (Psalm 89:3): "Where are your former mercies, O Lord, which you swore to David in your faithfulness?" Therefore, the Torah is called "very faithful". (Psalm 119:139) "My zeal has consumed me," etc. David said, "I am not jealous of the food and drink of the wicked, but I am jealous of all the good that you bring upon them, and how they have forgotten your Torah."
And likewise it says (Lamentations 3:17): "You have removed peace from my life," etc. Therefore it is said, "For they have forgotten your word, my enemy." (Psalm 119:139) "Your word is very pure," etc. What is meant by "very pure"? A parable: To what is this matter comparable? To a king who had a bowl of silver. He gave the silver to a refiner and said to him, "Refine it for me."
He put it in the crucible, refined it, and took it out. He said to him, "Refine it again." He refined it a second time, and a third time. So too, the Holy One, blessed be He, refined the Torah 49 times.
And it says (Proverbs 30:5), "Every word of God is pure." And it says (Psalm 12:7), "The words of the Lord are pure words," etc. Thus, the Torah is interpreted in 49 ways. Therefore it is said (Proverbs 30:5), "Every word of God is pure." And it says, "Your word is very pure."
