Passage
For the Lawe of his God is in his heart, and his steppes shall not slide.
For the Lawe of his God is in his heart, and his steppes shall not slide.
Psalms 37:29 The righteous men shall inherit the lande, and dwell therein for euer.
Psalms 37:30 The mouth of the righteous will speake of wisedome, and his tongue will talke of iudgement.
Psalms 37:31 For the Lawe of his God is in his heart, and his steppes shall not slide.
Psalms 37:32 The wicked watcheth the righteous, and seeketh to slay him.
Psalms 37:33 But the Lord wil not leaue him in his hand, nor condemne him, when he is iudged.
The verse centers on "lawe", "heart", "steppes", "shall", and "slide". It is saying that the verse draws attention to "lawe" and "heart", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 30's "The mouth of the righteous will speake..." into verse 32's "The wicked watcheth the righteous and seeketh...", so "lawe" and "heart" belong inside that flow. In Psalms context, the local focus is worship, trust, the LORD's kingship, and covenant mercy.
A plain takeaway is to answer the verse's own emphasis on "lawe" and "heart" with trust shaped by these words, not by a vague optimism outside the passage.
