Passage
their sword shall enter into their own heart, and their bows shall be broken.
their sword shall enter into their own heart, and their bows shall be broken.
Psalms 37:13 The Lord laugheth at him; for he seeth that his day is coming.
Psalms 37:14 The wicked have drawn out the sword, and have bent their bow, to cast down the afflicted and needy, to slay those that are upright in [the] way:
Psalms 37:15 their sword shall enter into their own heart, and their bows shall be broken.
Psalms 37:16 The little that the righteous hath is better than the abundance of many wicked;
Psalms 37:17 for the arms of the wicked shall be broken, but Jehovah upholdeth the righteous.
The verse centers on "sword", "shall", "enter", "heart", "bows", and "broken". It is saying that the verse draws attention to "sword" and "shall", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "The wicked have drawn out the sword..." into verse 16's "The little that the righteous hath is...", so "sword" and "shall" 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 "sword" and "shall" with trust shaped by these words, not by a vague optimism outside the passage.
