Our Speech

‎The mouth is a poetic use of one of the organs of speech and refers to the words or thoughts spoken by the righteous, that is, a good, honest person. Fountain of life is similar to “tree of life” used in 3:18. See there for comments. The expression is used in Psa 36.9 (Hebrew verse 10), where it refers to God as being the source or creator of all life. In 16:22 Wisdom is a fountain of life. In this verse the expression refers to the words of the righteous, perhaps because such people are identified with the wise and with wisdom.
