Taste and see that Jehovah is good. In this verse the Psalmist indirectly reproves men for their dulness in not perceiving the goodness of God, which ought to be to them more than matter of simple knowledge. By the word taste he at once shows that they are without taste; and at the same time he assigns the reason of this to be, that they devour the gifts of God without relishing them, or through a vitiated loathing ungratefully conceal them. He, therefore, calls upon them to stir up their senses, and to bring a palate endued with some capacity of tasting, that God's goodness may become known to them, or rather, be made manifest to them. The words literally rendered are, Taste and see, for the Lord is good; but the particle ky, ki, for, is taken exegetically. David's meaning, therefore, is, that there is nothing on the part of God to prevent the godly, to whom he particularly speaks in this place, from arriving at the knowledge of his goodness by actual experience. From this it follows, that they also are infected with the common malady of dulness. This doctrine is confirmed by the promise immediately added, Blessed is the man who trusteth in him; for God never disappoints the expectations of those who seek his favor. Our own unbelief is the only impediment which prevents him from satisfying us largely and bountifully with abundance of all good things.

O taste and see - This is an address to others, founded on the experience of the psalmist. He had found protection from the Lord; he had had evidence of His goodness; and he asks now of others that they would make the same trial which he had made. It is the language of piety in view of personal experience; and it is such language as a young convert, whose heart is filled with joy as hope first dawns on his soul, would address to his companions and friends, and to all the world around; such language as one who has had any special comfort, or who has experienced any special deliverance from temptation or from trouble, would address to others. Lessons, derived from our own experience, we may properly recommend to others; the evidence which has been furnished us that God is good, we may properly employ in persuading others to come and taste his love. The word "taste" here - טעם ṭâ‛am - means properly to try the flavor of anything, Job 12:11; to eat a little so as to ascertain what a thing is, 1-Samuel 14:24, 1-Samuel 14:29, 1-Samuel 14:43; Jonah 3:7; and then to perceive by the mind, to try, to experience, Proverbs 31:18.
It is used here in the sense of making a trial of, or testing by experience. The idea is, that by putting trust in God - by testing the comforts of religion - one would so thoroughly see or perceive the blessings of it - would have so much happiness in it - that he would be led to seek his happiness there altogether. In other words, if we could but get men to make a trial of religion; to enter upon it so as really to understand and experience it, we may be certain that they would have the same appreciation of it which we have, and that they would engage truly in the service of God. If those who are in danger would look to him; if sinners would believe in him; if the afflicted would seek him; if the wretched would cast their cares on him; if they who have sought in vain for happiness in the world, would seek happiness in him - they would, one and all, so surely find what they need that they would renounce all else, and put their trust alone in God. Of this the psalmist was certain; of this all are sure who have sought for happiness in religion and in God.
"Oh make but trial of His love;
Experience will decide
How bless'd are they - and only they -
Who in His truth confide."
Blessed is the man that trusteth in him - Compare the notes at Psalm 2:12.

O taste and see that the Lord is good - Apply to him by faith and prayer; plead his promises, he will fulfill them; and you shall know in consequence, that the Lord is good. God has put it in the power of every man to know whether the religion of the Bible be true or false. The promises relative to enjoyments in this life are the grand tests of Divine revelation. These must be fulfilled to all them who with deep repentance and true faith turn unto the Lord, if the revelation which contains them be of God. Let any man in this spirit approach his Maker, and plead the promises that are suited to his case, and he will soon know whether the doctrine be of God. He shall taste, and then see, that the Lord is good, and that the man is blessed who trusts in him. This is what is called experimental religion; the living, operative knowledge that a true believer has that he is passed from death unto life; that his sins are forgiven him for Christ's sake, the Spirit himself bearing witness with his spirit that he is a child of God. And, as long as he is faithful, he carries about with him the testimony of the Holy Ghost; and he knows that he is of God, by the Spirit which God has given him.

O taste, and see that the Lord is good,.... He is essentially, infinitely, perfectly, immutably, and solely good in himself; and he is communicatively and diffusively good to others: he is the author of all good, but not of any evil, in a moral sense; this chiefly regards his special grace and goodness through Christ: all the divine Persons in the Godhead are good; the Father is good, he has good designs towards his people, has provided good things for them, made good promises to them, and bestows good gifts on them: the Son is good; the good Shepherd that has laid down his life for the sheep; he is the fountain of all grace and goodness to his churches, and to particular believers; he has wrought a good work for them, the work of redemption, and he speaks a good word on their behalf in the court of heaven: the Spirit is good; he works good things in the hearts of the sons of men, and shows good things unto them; and gracious souls, such as the psalmist here calls upon, are capable of tasting and discerning how good the Lord is in some measure; see Psalm 119:103. While unregenerate, their taste is vitiated, and remains unchanged, and sin is what they feed upon with pleasure, and so detest everything that is good; but in conversion a new taste is given, so as to have a saving experimental knowledge of the grace and goodness of God in Christ, an application of it to them; and in such manner as to live upon it, and be nourished by it; and though this is not a superficial taste of things, like that of hypocrites, nor a single one only, being frequently repeated; yet it is but a taste in comparison of the enjoyment of it in the heavenly state; and every taste now influences and engages trust in the Lord, as follows;
blessed is the man that trusteth in him; See Gill on Psalm 2:12; the Targum renders it, "that trust in his word".

taste and see--try and experience.

O taste - Make trial, of it by your own experience of it. Good - Merciful and gracious.
