“And he told.” Mark 3:9 is unusual because it has two subjunctive verbs in the same sentence. Some commentators suggest that in this case the first subjunctive should be understood as an imperative (NIGCT; Word Biblical Commentary), the grammarian Danial Wallace says that while rare, that is an acceptable understanding of the subjunctive in some circumstances. It makes sense in this verse.
“crush.” The Greek thlibō (#2346 θλίβω) is to press (as grapes), press hard upon (Thayer, Lexicon). The versions are split between “press upon” and “crush,” but the people were already pressing upon him (v. 10). He wanted to be sure they did not crush him.
