Judges 16:14

Fastened it with the pin. Literally, “she struck with the pin.” This seems to have been a technical expression for the operation in weaving which beats the woof tightly into the warp. That this pin was evidently the weaver’s shuttle is inferred from the expression “pin of the beam” which follows.

Went away. The Hebrew verb used here basically means “to pull up” as in v. 3. The word was commonly used for pulling up tent stakes, from which usage it also took on the meaning “to depart.” Either meaning fits the context here. At any rate, in Samson’s efforts to free himself from the loom in which his hair was securely fastened, he tore the loom to pieces, and probably went off angrily with the web or unfinished cloth still in his hair and with the shuttle and parts of the loom clinging to it.
