OMG, if you know just simple Arabic then you can know what يعدون means just from the next words which is very clear and understood and which is وَيَوْمَ لَا يَسْبِتُونَ
which says when they don't rest which means "when going for fishing" then لَا تَأْتِيهِمْ which means the fish don't came when they go to work"وَيَوْمَ لَا يَسْبِتُونَ".
Well, I am not going to farther argue about the correct translation. I think I made some points, and that is totally up to you to have your own translation.
But, the correct translation is one thing, and weather or not God can order killing because of working on the Sabbath Day is another thing.
I think we need to be fair in our judgement to see the truth, even if that truth is against our desire.
Do you believe that God is that harsh to punish someone simply for working in vacation day and you believe God to be kind and merciful.
How you think and believe that God is kind and merciful while he order a law to kill someone for going to work, is working a bad deed.
Do you believe in God because that make sense to you or just a blind faith, in other words if God asked us to kill anyone who works on Sunday, will you support that law and kill people in order to please your God.
You are supporting that law since you believe it to be from God but I am just wondering how you believe it and still love that God which looks so harsh.
These are good questions, and for me requires long answer.
I think to understand Religion, we need to understand the circumstances and the time/place that a Revelation came. A Revelation and Law come in accordance with the requirements of the Age that those people lived in.
Now, if we think about the whole humanity on earth as One Body, generally, the Body of Humanity have been changing over time in terms of capacity to understand, civilization, sciences and social/economic system.
People who lived 6000 years were not at the same level as us today. Their way of life, everyday problems, their type of work, and many other things were quite primitive comparing to us.
It is believed that this World is like a school. Who is the Perfect Teacher?
God who manifested His Word, Will and commands through His messengers in every Age is like a Perfectly Wise Teacher of humanity.
A Perfect All-knowing Teacher would speak to a 5 year old child according to capacity of the child to understand. Same Perfect Teacher would speak differently to a child in grade 2, and again would talk differently to a grade 10 teenager...
A Perfect Teacher would not speak to a grade 2 student, with the level of grade 10 student.
Now, if we go back to analogy of Body of Humanity, those who lived 3000 years ago in comparison to Us, is like a 5 years old child to a teenager.
Therefore God who manifested Himself through Moses spoke to them in their own level of understanding. So for example it is written in Hebrew Scriptures:
"You shall not bow down to them or worship them; for I, the LORD your God,
am a jealous God...." Exodus 20:5
Is God really jealous? We don't believe He is, because in later Revelations, He manifested Himself differently. But He spoke to those people of old in accordance with their understanding, so His message may be accepted and understood by them.
And Just as their capacity to understand was different, so was their ways of life, and problems. So, for example, at the time of Jesus, it was men who worked outside, and women were dependent on men.
When Jesus came, the Jews were divorcing their wives for wrong reasons, and perhaps causing those women to sell their body, because in those days, there wasn't diversity of jobs for women the way it is now, and by divorcing them some of those women were forced to sell their bodies. "Under this circumstances" Jesus announced a restrict law for divorce.
But today we live in a different Age, those Laws of old are not required and suitable for our time. This is the reason they don't make sense now, but in their own time, and for the specific situation and circumstances, they were perfect and wise. That these Laws do not make sense for our time, is no proof they were not suitable in their own time, neither is a proof the Book got corrupted, neither is a proof the Book is not from a loving kind God.
