JMNT(i)
2 Now they [= the Pharisees and Herodians, of vs. 6] began narrowly watching and, at the side, kept on closely observing Him – [to see] if He will proceed tending, attentively serving, giving treatment to, beginning therapy with, prescribing ongoing treatment for, or curing and healing him on (= during) one of the sabbaths – so that they could accuse and bring charges against (down on) Him by a haranguing speech in a public assembly.
3 Then He begins saying to the man having the dried-up and withered hand, "Proceed to rise up, into the midst [of us]."
4 So he continues saying to them [either the entire group, or perhaps, the Pharisees], "On the sabbaths, is it allowed (permitted) to do good (or: to create or make something virtuous; to form inner harmonious perfection; to do an admirable act), or to do something harmful or worthless (to make something of bad quality; to do an evil act) – to heal (save; restore to health and its original condition; rescue) a soul (or: a breathing being), or to kill?" Yet, they kept on being silent (remained quiet).
