For thus saith the LORD, Ye have sold yourselves for nought; and ye shall be redeemed without money. For thus saith the Lord GOD, My people went down aforetime into Egypt to sojourn there; and the Assyrian oppressed them without cause. Now therefore, what have I here, saith the LORD, that my people is taken away for nought? they that rule over them make them to howl, saith the LORD; and my name continually every day is blasphemed. Therefore my people shall know my name: therefore they shall know in that day that I am he that doth speak: behold, it is I.
Israel had not been sold as a slave for monetary gain and she will not be redeemed with money as well. The Israelites went down at first into Egypt as guests; but subsequently they were abused. Later, the Assyrian oppressed them without cause, but not for monetary gain. Now once again God’s people are being tyrannized by oppressors who make no payment to the Lord. The overlords are delighted, and God’s name is blasphemed. But He will show Himself strong on behalf of His own, and they will know that He is all that He promised to be.
