The Lord hath sworn... — The principle of the Epistle to the Hebrews (Hebrews 6:13) is recognised here. Jehovah can swear by nothing less than that which is the symbol of His own greatness, identified with Himself.
I will no more give thy corn... — The words throw us back upon the early history of Israel, subject at any time to the desolating attacks of Midianites (Judges 6:4; Judges 6:11), Assyrians (Isaiah 16:9), and Philistines (2 Chronicles 28:18). The new blessing stands in special contrast with the curse of Deuteronomy 28:33; Deuteronomy 28:51.
