He called his name Noah, saying, This same shall comfort us, concerning our work and toil of our hands, because of the ground which the Lord hath cursed

There is a word in Genesis 5:28, 29 which we should carefully ponder in this connection. There we read that “Lamech lived an hundred eighty and two years, and begat a son: and he called his name Noah, saying, This same shall comfort us, concerning our work and toil of our hands, because of the ground which the Lord hath cursed.” This is the first mention of Noah in Scripture, and there is no doubt he had his name prophetically given him. His name signifies “Rest,” and was bestowed upon him by his father in the confident expectation that he would prove more than an ordinary blessing to his generation: he would be the instrument of bringing in that which would speak peace and inspire hope in the hearts of the elect—for the “us” and “our” (spoken by a believer) obviously refer to the godly line.

The words of the believing Lamech had respect unto what had been said in Genesis 3:15, and were also undoubtedly a prophecy which looked forward to Christ Himself, in whom it was to receive its antitypical fulfillment, for He is the true rest-giver (Matthew 11:28) and deliverer from the curse (Gal. 3:13). The full scope and intent of Lamech’s prophetic language is to be understood in the light of those blessings which were pronounced on Noah by God after the Flood blessings which, as we shall see, were infinitely more precious than that which their mere letter conveys. They were blessings to proceed through the channel of the everlasting covenant of grace and by means of the redemption which is in Christ Jesus. The proof of this is found in the fact that they were pronounced after sacrifice had been offered. This requires us to glance again at Genesis 8:20-22.
