“If the place which the Lord thy God has chosen to put his name there be too far from thee, then thou shalt kill of thy herd and of thy flock, which the Lord has given thee, as I have commanded thee, and thou shalt eat in thy gates to thy heart’s desire.”

To slaughter an animal, beast, or fowl and afterwards to eat their meat, as [Deuteronomy 12:21] states: "And you shall slaughter your cattle and your sheep."
לשחוט בהמה חיה ועוף ואחר כך יאכל בשרם, שנאמר: "וזבחת מבקרך ומצאנך" (דברים יב,כא).
