Moses is here to take the Hebrews away from Egypt, but he starts small. He’s just asking for a a little time off so they can go out to the wilderness and make a sacrifice to the Lord. Pharaoh decides to make life harder for asking, which could also make the Hebrews mad at Moses.
Freedom costs you something, but it isn’t God who wants paid. There are the people who lose your services. Or maybe they just envy your liberty. Either way, if you want to take a week off for some religious reason, it sets you apart and makes you different.
Even though we are not slaves today in the manner of the Hebrews back in Exodus, we do fear losing our jobs, and we are often saddled with debt. We are not really free. We are careful not to rock the boat.
I have been self employed for many years, largely because I lost my job over company immorality. I got free from sin, and they decided I had to go. Since then, I have been fired over political affiliation a couple of times, but not religious reasons. Maybe I need to work on that.
