Nope.
Exodus 20:8-11 8 “Remember the Sabbath day by keeping it holy. 9 Six days you shall labor and do all your work, 10 but the seventh day is a sabbath to the Lord your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. 11 For in six days the Lord made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the Lord blessed the Sabbath day and made it holy.
I am asking for Biblical evidence that "Saturday" is the Sabbath. This is evidence that the seventh day is the Sabbath. Not the same thing at all.
Exodus 16:29 Bear in mind that the Lord has given you the Sabbath; that is why on the sixth day he gives you bread for two days. Everyone is to stay where they are on the seventh day; no one is to go out.”
Once again this is referring to the seventh day, that is the seventh day from the New moon. That has nothing to do with Saturday.
Exodus 35:2 For six days, work is to be done, but the seventh day shall be your holy day, a day of sabbath rest to the Lord. Whoever does any work on it is to be put to death.
No, you have not shown that Saturday is the Sabbath.
