English Standard Version (ESV)
This passage shifts focus from God's protection of the righteous to the character of those who are righteous. After contrasting their outcomes with the wicked, the Psalmist now describes the inner life and outward expression of a godly person, emphasizing that their speech flows from wisdom and a commitment to justice, rooted in God's law within their hearts. This is immediately followed by the wicked observing and plotting against the righteous, highlighting the external pressures they face despite their inner integrity.
What we say can reveal the deepest parts of who we are. For the righteous, this isn't just about avoiding negativity, but about actively embodying wisdom.
This verse isn't just a suggestion; it's a descriptor of a righteous life. The righteous don't just think wise thoughts; their mouth speaks wisdom and their tongue speaks justice. This implies that wisdom and justice aren't just abstract concepts, but they flow out of a transformed inner life. It's about the overflow of what's truly in the heart. This is about sincerity and truth in speech, not just a superficial appearance of godliness.
Where does this wisdom and justice truly come from? It's not simply innate, but deeply connected to God's own truth.
The commentators highlight that the 'wisdom' and 'justice' spoken by the righteous are not their own invention. They stem from 'God's judgment, word, or law' dwelling within them. This inner cultivation of God's truth is what directs their speech. It means their words are serious, edifying, and aligned with divine principles, a stark contrast to vain or wicked talk.
