26 The word “wicked” could be taken as a vocative (cf. , , , “O wicked man”); but since the next line refers to the wicked this is unlikely. It serves better as an adverbial accusative (“like the wicked”).
27 The saying warns that it is futile and self-defeating to mistreat God’s people, for they survive—the wicked do not. The warning is against a deliberate, planned assault on their places of dwelling.
28 The clause beginning with כִּי (ki) could be interpreted as causal or conditional; but in view of the significance of the next clause it seems better to take it as a concessive clause (“although”). Its verb then receives a modal nuance of possibility. The apodosis is then “and he rises up,” which could be a participle or a perfect tense; although he may fall, he gets up (or, will get up). The righteous may suffer adversity or misfortune any number of times—seven times here—but they will “rise” for virtue triumphs over evil in the end (R. N. Whybray, Proverbs [], 140).
29 The verb could be translated with an English present tense (“are brought down,” so ) to express what happens to the wicked in this life; but since the saying warns against being like the wicked, their destruction is more likely directed to the future.

In other versions

Lie not in wait as a wicked man against the dwelling of the righteous;

do no violence to his home;

for the righteous falls seven times and rises again,

but the wicked stumble in times of calamity.

Do not lurk like a thief near the house of the righteous,

do not plunder their dwelling place;

for though the righteous fall seven times, they rise again,

but the wicked stumble when calamity strikes.

Don’t set an ambush, you wicked one,

at the camp of the righteous man;

don’t destroy his dwelling.

Though a righteous person falls seven times,

he will get up,

but the wicked will stumble into ruin.

Don’t wait in ambush at the home of the godly,

and don’t raid the house where the godly live.

The godly may trip seven times, but they will get up again.

But one disaster is enough to overthrow the wicked.

Do not lie in wait like an outlaw against the home of the righteous;

do not do violence to his dwelling place.

For seven times the righteous will fall, but he will rise,

but the wicked will be overthrown by calamity.

Lay not wait, O wicked man, against the dwelling of the righteous;

Spoil not his resting place:

For a just man falleth seven times, and riseth up again:

But the wicked shall fall into mischief.
