Passage
Blessed is the man that trusteth in Jehovah, and whose trust Jehovah is.
Blessed is the man that trusteth in Jehovah, and whose trust Jehovah is.
Jeremiah 17:5 Thus saith Jehovah: Cursed is the man that trusteth in man, and maketh flesh his arm, and whose heart departeth from Jehovah.
Jeremiah 17:6 For he shall be like the heath in the desert, and shall not see when good cometh, but shall inhabit the parched places in the wilderness, a salt land and not inhabited.
Jeremiah 17:7 Blessed is the man that trusteth in Jehovah, and whose trust Jehovah is.
Jeremiah 17:8 For he shall be as a tree planted by the waters, that spreadeth out its roots by the river, and shall not fear when heat cometh, but its leaf shall be green; and shall not be careful in the year of drought, neither shall cease from yielding fruit.
Jeremiah 17:9 The heart is deceitful above all things, and it is exceedingly corrupt: who can know it?
The verse centers on "blessed", "trusteth", "jehovah", and "whose". It is saying that the verse draws attention to "blessed" and "trusteth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 6's "For he shall be like the heath..." into verse 8's "For he shall be as a tree...", so "blessed" and "trusteth" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "blessed" and "trusteth" with trust shaped by these words, not by a vague optimism outside the passage.
