Passage
Try mee, O God, and knowe mine heart: prooue me and know my thoughtes,
Try mee, O God, and knowe mine heart: prooue me and know my thoughtes,
Psalms 139:21 Doe not I hate them, O Lord, that hate thee? and doe not I earnestly contend with those that rise vp against thee?
Psalms 139:22 I hate them with an vnfained hatred, as they were mine vtter enemies.
Psalms 139:23 Try mee, O God, and knowe mine heart: prooue me and know my thoughtes,
Psalms 139:24 And consider if there be any way of wickednes in me, and leade me in the way for euer.
The verse centers on "knowe", "mine", "heart", "prooue", and "thoughtes". It is saying that the verse draws attention to "knowe" and "mine", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 22's "I hate them with an vnfained hatred..." into verse 24's "And consider if there be any way...", so "knowe" and "mine" 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 "knowe" and "mine" with trust shaped by these words, not by a vague optimism outside the passage.
