28:13 The head - The chief of all people in power, or at least in dignity and privileges; so that even they that are not under thine authority shall reverence thy greatness and excellency. So it was in David's and Solomon's time, and so it should have been much oftner and much more, if they had performed the conditions.

28:1-14 This chapter is a very large exposition of two words, the blessing and the curse. They are real things and have real effects. The blessings are here put before the curses. God is slow to anger, but swift to show mercy. It is his delight to bless. It is better that we should be drawn to what is good by a child-like hope of God's favour, than that we be frightened to it by a slavish fear of his wrath. The blessing is promised, upon condition that they diligently hearken to the voice of God. Let them keep up religion, the form and power of it, in their families and nation, then the providence of God would prosper all their outward concerns.
