Luke 13:8
You hypocrites! Doesn't each of you on the Sabbath untie your ox or donkey from the stall and lead it out to give it water? — the Sabbath-animal-care precedent established by unanimous practice undermines the Sabbath-healing objection. If untying an animal to lead it to water is acceptable Sabbath work, then untying a daughter of Abraham from eighteen years of Satanic bondage is surely more so.
