It is about fountain of life at Proverbs 13:13 which goes this way ” Whoso despiseth the word shall be destroyed but he that feareth the commandment shall be rewarded”
Matthew Henry’ commentary : Those that prefer the rules of carnal policy before divine precepts, and the allurements of the world and the flesh before God’s promises and comforts, despise His word.He that fears the commandment, that stands in awe of God, has a reverence for His word, is afreaid of displeasing God and incurring the penalties annexed to the commandment, shall be rewarded for his godly fear.
