Your words have been stout {m} against me, saith the LORD. Yet ye say, What have we spoken so much against thee?

(m) The Prophet condemns them of double blasphemy against God: first, in that they said that God had no respect for those that served him, and next, that the wicked were more in his favour than the godly.

Jamieson-Fausset-Brown Bible Commentary

13-18. He notices the complaint of the Jews that it is of no profit to serve Jehovah, for that the ungodly proud are happy; and declares He will soon bring the day when it shall be known that He puts an everlasting distinction between the godly and the ungodly.

words . stout-Hebrew, "hard"; so "the hard speeches which ungodly sinners have spoken against Him" (Jude 15) [Henderson].

have we spoken-The Hebrew expresses at once their assiduity and habit of speaking against God [Vatablus]. The niphal form of the verb implies that these things were said, not directly to God, but of God, to one another (Eze 33:20) [Moore].

Matthew Henry's Concise Commentary

3:13-18 Among the Jews at this time, some plainly discovered themselves to be children of the wicked one. The yoke of Christ is easy. But those who work wickedness, tempt God by presumptuous sins. Judge of things as they will appear when the doom of these proud sinners comes to be executed. Those that feared the Lord, spake kindly, for preserving and promoting mutual love, when sin thus abounded. They spake one to another, in the language of those that fear the Lord, and think on his name. As evil communications corrupt good minds and manners, so good communications confirm them. A book of remembrance was written before God. He will take care that his children perish not with those that believe not. They shall be vessels of mercy and honour, when the rest are made vessels of wrath and dishonour. The saints are God's jewels; they are dear to him. He will preserve them as his jewels, when the earth is burned up like dross. Those who now own God for theirs, he will then own for his. It is our duty to serve God with the disposition of children; and he will not have his children trained up in idleness; they must do him service from a principle of love. Even God's children stand in need of sparing mercy. All are righteous or wicked, such as serve God, or such as serve him not: all are going to heaven or to hell. We are often deceived in our opinions concerning both the one and the other; but at the bar of Christ, every man's character will be known. As to ourselves, we have need to think among which we shall have our lot; and, as to others, we must judge nothing before the time. But in the end all the world will confess that those alone were wise and happy, who served the Lord and trusted in Him.
