a man's emission of semen, and the act of intercourse that releases it, named in the fixed legal phrase "emission of seed"
The word is built from the ordinary verb for lying down (שָׁכַב), and its basic idea is something laid down. In the purity laws it never stands alone: it is always joined to the word for seed (זֶרַע), and the two work as one fixed expression, usually translated "emission of semen".
Two things can be in view, and the wording of each law tells a reader which:
- Four laws speak of it going out from a man, or lying on a garment or a piece of leather, which is the semen itself as a substance.
- Three speak of a man lying with a woman "an emission of seed", which is the act of intercourse named by what it releases.
What holds the two together is that Israel's priests were interested in the deposit rather than in the encounter. Naming the emission let them write rules that could be applied without anyone having to describe what happened: something left the body, so a wash and a wait until evening follow. In Leviticus 15 that is an ordinary, blameless matter, and a married couple falls under the same simple rule as anyone else. Only where the law turns to who a man may not approach, as in Leviticus 19:20 and Numbers 5:13, does the same wording carry a charge with it.
A sister noun from the same root, שְׁכֹבֶת, covers nearly the same ground when a law wants to pin the emission on one particular man. Numbers 5 uses this word in verse 13 and that one in verse 20 for the very same suspected act.

Whether the phrase "emission of seed" names the semen as a substance, the act of ejaculation during intercourse, or the two fused into a single legal idiom.
