Leviticus 10:12-20 and Luke 15:1-7 (GWT)

Leviticus 10:12-20
The Death of Nadab and Abihu
12  Moses told Aaron and his surviving sons Eleazar and Ithamar, “Take the grain offering left over from the offering by fire to the Lord. Make unleavened bread, and eat it next to the altar because it is very holy. 
13  Eat it in a holy place because it is the part of the offering by fire to the Lord that belongs to you and your children. That is the command I received. 
14  Also eat the breast presented to the Lord and the thigh that was given as a contribution. You and your sons and daughters may eat them in a clean place because they are your part of the fellowship offerings from the Israelites. 
15  They will bring the thigh given as a contribution, the breast presented to the Lord, and the fat that is to be burned and present them to the Lord. These parts will belong to you and your children. This will be a permanent law, as the Lord has commanded.”
16  Moses tried to find out what had happened to the male goat that was supposed to be the offering for sin. To his surprise, it had already been burned. So he became angry with Eleazar and Ithamar, Aaron’s surviving sons. 
17  He asked them, “Why didn’t you eat the offering for sin in the holy place? It is very holy and was given to you to take away the sins of the congregation and to make peace with the Lord for them. 
18  Since its blood was not brought inside the holy place, you certainly should have eaten it there, as I commanded.”
19  Aaron answered Moses, “Today they sacrificed their offering for sin and their burnt offering in the Lord’s presence, and look what happened to me. If I had eaten the offering for sin today, would the Lord have approved?”
20  When Moses heard this, he was satisfied.

Luke 15:1-7
The Parable of the Lost Sheep
1   All the tax collectors and sinners came to listen to Jesus. 
2   But the Pharisees and the experts in Moses’ Teachings complained, “This man welcomes sinners and eats with them.”
3   Jesus spoke to them using this illustration: 
4   “Suppose a man has 100 sheep and loses one of them. Doesn’t he leave the 99 sheep grazing in the pasture and look for the lost sheep until he finds it? 
5   When he finds it, he’s happy. He puts that sheep on his shoulders and 
6   goes home. Then he calls his friends and neighbors together and says to them, ‘Let’s celebrate! I’ve found my lost sheep!’ 
7   I can guarantee that there will be more happiness in heaven over one person who turns to God and changes the way he thinks and acts than over 99 people who already have turned to God and have his approval.”
