The chapter ends very graciously, in showing the Church, under the similitude of the husbandman, how the Lord takes care of his household. And as Jesus hath sweetly set forth the same blessed truths, under the same imagery; we cannot be at a loss to apprehend the whole of the instruction. Ye are God's husbandry, said the apostle; and Jesus himself saith, I am the vine, ye are the branches. Oh! for grace to be thus favoured, and to know that we are brought into the vineyard, the Church of the Lord of hosts. Isa 5:7; 1 Corinthians 3:9; John 15:1, etc.
Isaiah 28:23-29
23 Give ye ear, and hear my voice; hearken, and hear my speech.
24 Doth the plowman plow all day to sow? doth he open and break the clods of his ground?
25 When he hath made plain the face thereof, doth he not cast abroad the fitches, and scatter the cummin, and cast in the principalc wheat and the appointed barley and the rie in their place?
26 For his God doth instruct him to discretion, and doth teach him.
27 For the fitches are not threshed with a threshing instrument, neither is a cart wheel turned about upon the cummin; but the fitches are beaten out with a staff, and the cummin with a rod.
28 Bread corn is bruised; because he will not ever be threshing it, nor break it with the wheel of his cart, nor bruise it with his horsemen.
29 This also cometh forth from the LORD of hosts, which is wonderful in counsel, and excellent in working.
