retire from what? If it is from worldly affairs than I suppose when you are born. God didn’t lead the children of Israel into the wilderness to put a yoke back on them . He wanted to show them that if they believed in Him then He would take care of them . They formerly lived as slaves in Egypt , working for their bread under the tyranny of Pharoah.
I consider the slaves in Egypt analogous to the workers of this world <- the whore of babylon. “Lifes a bitch and then you die ” is a famous cliche and for good reason . How hard is it to work in society for a decent wage ? I mean if you aren’t your own boss or own your own company it’s extremely hard to make ends meet , and your lucky if you make it to age 65 in good health. It’s like you must sacrifice your health if you want to make a living
