nega

This word comes from the ordinary verb for touching or striking, and as a noun it names the thing that lands when contact is made. In this first range it is not a random misfortune but a blow with a sender behind it: a plague on a household, an affliction on the body, a stroke laid on a person because of sin. The Hebrew keeps the two ideas of touch and impact fused in one word, so the same term can be a light touch of warning or a crushing blow, depending on the moment.

Because the blow is read as coming from God, the word carries the weight of judgment and of discipline together. The same stroke that ruins Pharaoh's house can be:

• the correction a father gives a wayward son
• the danger a trusting person is kept safe from
• the suffering an innocent one bears for others

It can even turn inward, naming the private ache a worshipper carries in his own heart.

The senses here differ by who receives the blow and why, not by what the blow is. In every case it is an affliction that someone reads as having God's hand on it. A narrower legal use sits alongside these: in a courtroom setting the same word names a case of bodily injury, the kind of assault a judge must rule on.

In the law of Leviticus this same word turns technical. It names not a disease in general but the visible mark itself, the one brought to a priest for a verdict:

• the patch of skin
• the streak in a garment
• the greenish or reddish spot in the plaster of a house wall

The priest is told to look at the mark, measure how deep it sits, shut it away, watch whether it spreads, and only then rule the person, the cloth, or the house clean or unclean.

A key point often missed is that this word is the wider category, not the diagnosis. It names the suspicious spot that is examined, while a different Hebrew word (צרעת) names the actual defiling disease that the examination may or may not confirm. So the mark is the thing brought in for a ruling, and only some marks turn out to be the dreaded condition; the rest are released as clean.

The striking thing is that the word reaches beyond the body. A garment and a house can carry such a mark too, and the same inspection applies. The law even says God himself may place such a mark in a house, which is why readers across the centuries have felt this priestly sense and the sense of a divine blow to be two sides of one word: a spot that looks as if it were struck onto a surface, now made the object of careful inspection.
