Mat 12:11 What man is there among you, if he has one sheep, and if it falls into a pit on the sabbath day, will he not lay hold of it, and lift [it] out?

Isn't in interesting that Christ always uses examples regarding farming and livestock despite that fact that he personally was a carpenter. He never illustrates his ideas with examples from carpentry. Why? The reason is that Christ was speaking to all people at all time. People may or may not be able to related to a profession like carpentry, but everyne understands about growing things and taking care of animals, even if you aren't a farmer.

Also notice that Christ never disparages people looking after their self-interest. Christ ask us to imagine that the sheep that has fallen into a well is the only sheep we have. It is not part of a large herd. This makes it both valuable property and something of a pet. Christ considers it only natural that someone would rescue their sheep despite the laws regarding the Sabbath because that sheep is valuable.

"Fall into" is empiptô, which means "to fall in" and "to fall on."

"Pit" is bothunos, which means "pit" and "well." It is a version of bathuno, which means "to make deep," "deep," and, interestingly, "poverty."

"Lay hold" is krateô, which means "to be strong," "to prevail," "to get possession of," and "to lay hold of."

"Lift out" is egeirô, which means "to waken," "to rouse," "to raise," and "to be excited by passion.

I like the way that the author illustrating the ideas of "laying ahold of" and "rousing" with the ideas of "being strong" and "getting excited." You would get excited if an animal fell in a pit and you would be strong.
