a curse that takes effect: the blight that settles on someone's work, land, or household and drains it of any increase
Hebrew has several words for a curse, and this one names the outcome rather than the words. It is built from the verb meaning "to put under a curse" (אָרַר), and where that verb is the act, this noun is what is left once the act has landed: crops that never come in, work that comes to nothing, a house that never prospers.
All five appearances describe the same thing happening to something that should have produced:
- everything a person sets his hand to falls apart (Deuteronomy 28:20)
- the blessings the priests pronounce are turned inside out (Malachi 2:2)
- a whole nation watches its harvest eaten away (Malachi 3:9)
- a wicked man's household never comes to anything (Proverbs 3:33)
- a man who refuses the poor collects one ruin after another (Proverbs 28:27)
In four of the five the LORD is plainly the one who sends it, and it is set directly against blessing. Malachi 2:2 has God cursing the very blessings the priests hand out, and Proverbs 3:33 puts this curse on the wicked man's house opposite the blessing on the righteous man's home. Only Proverbs 28:27 leaves the source unnamed.
That focus on effect is what separates it from the ordinary Hebrew word for a curse (קְלָלָה), which usually points at the words said or the shameful name a person is left with, and from the sworn curse of a broken oath (אָלָה), which is a penalty a person calls down on himself.
