'Number' in the Bible

Then they said, "What shall be the trespass offering which we shall return to him?" They said, "Five golden tumors, and five golden mice, [according to] the number of the lords of the Philistines; for one plague was on you all, and on your lords.

and the golden mice, according to the number of all the cities of the Philistines belonging to the five lords, both of fortified cities and of country villages, even to the great stone, whereon they set down the ark of Yahweh, [which stone remains] to this day in the field of Joshua of Beth Shemesh.

and David arose and went, he and his men, and killed of the Philistines two hundred men; and David brought their foreskins, and they gave them in full number to the king, that he might be the king's son-in-law. Saul gave him Michal his daughter as wife.

The number of the days that David lived in the country of the Philistines was a full year and four months.
