Definition: But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they [are] holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat [for] an offering made by fire, for a sweet savour unto the LORD.

Explanation: Okay, let’s break down this verse from Numbers 18:17. It's a really important rule about how animals are to be treated before they’re sacrificed in Jewish tradition. Here’s what it means in simpler terms: Essentially, it says that the most valuable animal – the firstling – must be offered as a sacrifice. Let’s unpack that further: “Numbers 18:17” : This is the verse itself, referencing a specific event in the Old Testament. “But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat…” – This means the most valuable animal – the one that’s the best and most prized – must be offered. It's not just any animal; it's the best animal. “…thou shalt not redeem; they [are] holy: thou shalt sprinkle their blood upon the altar, and shalt burn their fat [for] an offering made by fire, for a sweet savour unto the LORD.” – This is where it gets really important. Here's what’s happening: “thou shalt not redeem” : This is crucial . Don't try to save this animal! It’s meant to be offered as a sacred gift. “…sprinkle their blood upon the altar…” : This means they must be sprinkled with blood – a symbolic act of offering. “…and shalt burn their fat [for] an offering made by fire…” : This is the core of the ritual. The animal's fat (the meat) is to be burned in a special way, creating a sweet smell that’s meant to please God. It's like a sacrifice of deliciousness. “…for a sweet savour unto the LORD.” : The goal is to make God happy and pleased with this offering. It’s about demonstrating reverence and gratitude. So, what’s the point? This rule was established in ancient times to ensure that offerings were made with genuine religious intent – that is, with a sincere desire to honor God. It’s a way of acknowledging that the animals were special because they represent God's bounty and are meant for His use. It emphasizes the importance of the offering being a heartfelt act of worship. In short, it’s a very serious rule about giving respect and gratitude to God through sacrifice.
