He is in the way of life that keepeth instruction: but he that refuseth reproof erreth.
– Proverbs 10:17
Life in the Proverbs is a quality of life and not a quantity of life. Life also includes thoughts of the spiritual and the afterlife. The way of life is to them who keepeth instruction. Proverbs emphasizes the importance of hearing instruction but also the importance of retaining it (Proverbs 3:1-2, 18; 4:4, 13). The contrast is made between keeping and refusing, or forsaking, as the word indicates. To err is to go astray and we know it is ultimately to come to ruin (Proverbs 15:10; 29:1).
