The Lord preserveth all them that love him - He keeps them; watches over them; defends them; makes them the object of his care. See Psalm 31:20, note, Psalm 31:23, note; Psalm 97:10, note.

But all the wicked will he destroy - All that are found ultimately to be wicked; all that on the final trial deserve to be classed with the wicked. See Psalm 9:17, note; Psalm 11:6, note; Matthew 25:46, note.

The Lord preserveth - He is the keeper of all them that love him.

But all the wicked will he destroy - They call not upon him; they fight against him, and he will confound and destroy them. There is something curious in the שומר shomer, the keeper or guardian of the pious; he is שמיד shamid, the destroyer of the wicked. The first word implies he is continually keeping them; the second, that he causes the others to be destroyed.

The Lord preserveth all them that love him,.... All do not love Christ, none but those that are born again, and believe in him: love to Christ is a fruit of the Spirit, and accompanies faith in him; it flows from the love of Christ shed into the heart, and from a view of his loveliness, and a sense of his benefits; and, where it is true and genuine, it is superlative and sincere, and shows itself by a regard to its truths and ordinances, to his people, ways, and worship: and such the Lord preserves often in times of public calamity; and from the evil of sin, the dominion of it; from Satan's temptations, from being devoured and destroyed by him; and from a final and total falling away; he preserves them to his kingdom and glory, which is promised to them that love him;

but all the wicked will he destroy; he will consume them from off the earth, so that the wicked shall be no more; he will destroy the man of sin, and all his adherents; all the enemies of Christ, those that do not love him, but oppose him, his Gospel, kingdom, and interest; the beast and false prophet, with all that attend them, shall be cut off; the day of the Lord, like an oven, shall burn up all that do wickedly, and shall leave them neither root nor branch: this will especially be true at the day of judgment, when the wicked shall be ordered to everlasting fire; and they shall go into eternal punishment, when they shall be turned into hell; and all the nations that forget God. Kimchi interprets this of future time, when there shall not be a wicked man left in the world, and compares it with Malachi 4:1.

The LORD preserveth all them that love him: but all the wicked will he destroy.

20. Those who fear Him (Ps 145:19) are those who are here said to love Him.

145:10-21 All God's works show forth his praises. He satisfies the desire of every living thing, except the unreasonable children of men, who are satisfied with nothing. He does good to all the children of men; his own people in a special manner. Many children of God, who have been ready to fall into sin, to fall into despair, have tasted his goodness in preventing their falls, or recovering them speedily by his graces and comforts. And with respect to all that are heavy laden under the burden of sin, if they come to Christ by faith, he will ease them, he will raise them. He is very ready to hear and answer the prayers of his people. He is present every where; but in a special way he is nigh to them, as he is not to others. He is in their hearts, and dwells there by faith, and they dwell in him. He is nigh to those that call upon him, to help them in all times of need. He will be nigh to them, that they may have what they ask, and find what they seek, if they call upon him in truth and sincerity. And having taught men to love his name and holy ways, he will save them from the destruction of the wicked. May we then love his name, and walk in his ways, while we desire that all flesh should bless his holy name for ever and ever.
