So what are these commandments that Jesus is speaking of? There 613 (give or take) commandments in the Old Testament referred to as "the Law". Many of these commands were given to the nation of Israel to make them a holy people as we described above. Others, like the 10 commandments are clearly meant for all people at all times. Great care must be taken to discern which laws were meant for the nation of Israel and those meant for all man. To be clear though, all 613 laws need to be considered in view of how Jesus came to "fulfill them"

An obvious example are the "laws" regarding the Jewish Passover celebration. When Jesus became the "sacrificial lamb", he fulfilled those laws and Christians have no need to sacrifice animals on alters. The same for the "laws" regarding atonement. When Jesus died for our sins, the need to "atone" annually for our sins through those rituals was nullified, because forgiveness through grace by faith fulfilled those laws
