Psalms 16:5 - Coke's Commentary on the Holy Bible

The Lord is the portion, &c.— See the note on Psalms 11:6. Thou maintainest my lot, means that God had preserved for him the glory to which he was to be exalted in the quality of Messiah. See Psalms 2:8. Lot is here put for heritage, in allusion to the division which was made of the land of Canaan by lot. The same allusion is carried on in the next verse; where lines signify the lot or tract of land which it was anciently the custom to divide by lines. The goodly heritage was, first, the glory to which he was advanced by his ascension; and, secondly, the establishment of his kingdom throughout the world.
