The LORD knoweth the days of the upright: and their inheritance shall be for ever.
Ver. 18. The Lord knoweth the days of the upright] In bonum novit, Psalms 1:6 id est prolongat, saith Kimchi; he knoweth, that is, he acknowledgeth, approveth, hath a gracious regard unto, their days and the events thereof; he hath decreed to a minute how long they shall suffer, and what happiness shall succeed their sufferings.
And their inheritance shall be for ever] Here long; and hereafter eternal. What they want here, shall be there made up abundantly.
