I understand. However, I'll go back to what Jesus said about the Sabbath and how it was interpreted wrongly. Let's see: (back to Luke 13 again...by the way, every time I read something again I learn something very good...)
"One Sabbath Jesus was teaching in one of the synagogues, "
(Teaching in one of the synagogues...)
11and a woman there had been disabled by a spirit for eighteen years. She was hunched over and could not stand up straight.
12When Jesus saw her, He called her over and said, “Woman, you are set free from your disability.”
13Then He placed His hands on her, and immediately she straightened up and began to glorify God.
14But the synagogue leader was indignant that Jesus had healed on the Sabbath. “
(The synagogue LEADER...)
****"There are six days for work,” he told the crowd. “So come and be healed on those days and not on the Sabbath.”
15“You hypocrites!” the Lord replied. “Does not each of you on the Sabbath untie his ox or donkey from the stall and lead it to water?
16Then should not this daughter of Abraham, whom Satan has kept bound for eighteen long years, be released from her bondage on the Sabbath day?” (Luke 13)***
So it would be interesting to see more about this in reference to the 613 laws thereof. Notice, please: it was the synagogue LEADER who assailed Jesus about healing on the Sabbath. Why did he criticize Jesus? Yet Jesus called those along with the synagogue LEADER
hypocrites.
(By the way, to an extent the custom is practiced today to an extent among some rather religious populations, you probably know this though.)
I'm looking up about the 613 laws on chabad.org and it offers some interesting points which I may go into later.
