to be undisturbed: to have trouble stay away from you, and so to live quietly and do well
At its core this verb describes a condition rather than an activity: nothing is coming at you. Job says it plainly when he denies it of himself, stacking it beside two other words in one breath, being still (שָׁקַט) and having rest (נוּחַ), and then adding that trouble came anyway. To be in this state is simply to be left alone by what could hurt you.
From that center the word slides naturally toward flourishing, because a life nothing interferes with is a life that goes well. That is why English versions swing between "at ease" and "prosper" for the very same word. Jeremiah's complaint keeps the two ideas side by side: the way of the wicked succeeds, using a different verb for an undertaking that goes through (צָלֵחַ), and the treacherous are untroubled, using ours.
The word itself passes no verdict, and that is easy to miss, because four of its five appearances sting:
- robbers' tents stand untouched while the honest suffer;
- everyone who deals treacherously goes unbothered;
- the enemies who sacked Zion are the ones now doing well;
- and only in Psalm 122 is it a blessing prayed over the friends of Jerusalem, where its sound chimes against peace (שָׁלוֹם) and the city's own name.
The verb is rare, five times in poetry, but its family is not. The adjective for a person who is untroubled (שָׁלֵו) and the noun for that untroubled condition (שַׁלְוָה) carry the same idea across Job, Psalms, Proverbs, Ezekiel, and Daniel, and there the double edge is just as clear: the same settled comfort is God's gift in one verse and the self-satisfaction that ruins people in the next.
