For the word of the LORD [is] right; and all his works [are done] in truth.
Ver. 4. For the word of the Lord is right] Every word of God is pure and precious, Proverbs 30:5; his commandment holy, and just, and good, Romans 7:12; but by word here we are to understand God's counsel and decree concerning the creation and government of the world, which is unquestionably right, and agreeable to sound reason, and therefore they are to blame that dislike his doings. If any evil befall them, the saints confess God's righteousness, and praise him, as Isa 12:1 Psalms 10:1, saith Kimchi here.
And all his works are done in truth] Or, in faith; that is, in faithfulness, without deceit or fickleness. This is to be understood as the execution of God's decree, all is done well, and equitably.
