Whenever Man sinned, an innocent animal would have to be killed, and by its blood that sin was cleansed. A sacrifice had to be constantly given, for we are constantly sinning.
The Jewish people under Moses sacrificed twice a day; in the morning at 10am, and in the afternoon, at 3pm. At the time of sacrifice, a priest would blow the shofar, a Jewish horn. At that moment, the lamb’s throat was slit, and all the religious Jews would pause for a moment, begging God to remember the final and perfect sacrifice He’d promised to Abraham. This practice continued for years.
About 2,000 years ago, Jesus hung on a cross. At 3pm, the shofar sounded for the sacrifice, and Jesus said, ‘it is finished.’ Then He died.
The daily sacrifices weren’t needed anymore, for He was the last, perfect, and sinless sacrifice.
