'Slaughter' in the Bible

Abijah and his people defeated them with a great slaughter, so that 500,000 chosen men of Israel fell slain.

For there were many in the assembly who had not consecrated themselves; therefore, the Levites were over the slaughter of the Passover lambs for everyone who was unclean, in order to consecrate them to the Lord.

Now slaughter the Passover animals, sanctify yourselves and prepare for your brethren to do according to the word of the Lord by Moses.”
