In this chapter, the writer finishes describing how Jesus's sacrifice was better than the sacrifices offered in the Temple. (See: [[rc://en/tw/dict/bible/kt/lawofmoses]])
Some translations set poetry farther to the right than the rest of the text to show that it is poetry. The ULB does this with the poetry in 10:5-7, 15-17, 37-38, which is from the Old Testament.
Holy living is important for Christians. God will hold people accountable for how they lived their Christian lives. Even though there will not be eternal condemnation for Christians, ungodly actions do and will have consequences. In addition, faithful living will be rewarded. (See: [[rc://en/tw/dict/bible/kt/holy]], [[rc://en/tw/dict/bible/kt/godly]] and [[rc://en/tw/dict/bible/kt/faithful]] and [[rc://en/tw/dict/bible/other/reward]])
The sacrifices themselves had no redeeming power. They were effective because they were a display of faith, which was credited to the person offering the sacrifice. It is ultimately the sacrifice of Jesus that "takes away sins." (See: [[rc://en/tw/dict/bible/kt/redeem]] and [[rc://en/tw/dict/bible/kt/faith]])
It is unclear whether this prophecy was being fulfilled as the author was writing or whether it was to occur later. The translator should try to avoid making a claim about the time this covenant begins. (See: [[rc://en/tw/dict/bible/kt/prophet]] and [[rc://en/tw/dict/bible/kt/covenant]])
