The Lord preserveth all them that love him - He keeps them; watches over them; defends them; makes them the object of his care. See Psalms 31:20, note, Psalms 31:23, note; Psalms 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 Psalms 9:17, note; Psalms 11:6, note; Matthew 25:46, note.
