Really so on God's day of rest he:
Flooded the earth killing all creatures except those on the Ark,
Punished the inhabitants of Babel for wanting to be closer to him thus sowing the seeds for millennia of poor communication and discord.
Destroyed the towns of Soddom and Gomorrah turning Lot's wife into a Pillar of salt as he did so.
Caused the hundred year old Abraham to bear a son Issac.
Appeared to Moses as a burning bush
Changed Aarons Rod into a Serpant
Inflicted the plagues of Egypt
Divided the Red Sea, sending it crashing back to drown Pharroh's army.
Cared for the wanderers in the desrt for 40 years by sending them manna, sending water to them where Moses struck a rock with his staff (twice) and sweetening the water at Marah.
Issued the ten commandments... twice. The second one apparently with copy errors.
Consumed Nadab and Abihu with fire not to mention the people at Tabirah and Korah and Kadesh.
Made Arron's Rod bud.
Animated the brazen serpent
Caused Balaam Ass to speak
Divided the river Jordan
Toppled the walls of Jerico
Stayed the sun and the moon for Joshua and sent him a hailstorm
Immolated various folk for looking at ot touching the arc of the covenant.
Blinded and cured the Syrians
Raised the dead a couple of times.
Persecuted Jonah - on a bet.
It certainly doesn't sound restfull to me.
I could go on with more Old testament Death and destruction but lets skip forward to impregnating a virgin without prior consent cos I just love that one.
Anyway here's a big old list -

If he did all this on his one day of rest then tell me why didn't he send manna on the sabbath?
