“Make up your minds!
Do not prepare
θέτε οὖν ἐν ταῖς καρδίαις ὑμῶν μὴ προμελετᾶν ἀπολογηθῆναι·
Luke indicated that Jesus told them to make up or settle their minds or hearts (θέτε οὖν ἐν ταῖς καρδίαις ὑμῶν), so that they did not have to prepare their defense ahead of time (μὴ προμελετᾶν ἀπολογηθῆναι). This is unique use by Luke of the term προμελετᾶν, that means to premeditate, meditate beforehand, or prepare. Equivalent passages to this can be found in Matthew, chapter 10:19, and Mark, chapter 13:11. Mark indicated that Jesus told his disciples not to worry beforehand or be anxious about what to say (μὴ προμεριμνᾶτε τί λαλήσητε), when they were handed over and brought to trial (καὶ ὅταν ἄγωσιν ὑμᾶς παραδιδόντες). Matthew indicated that Jesus told his disciples not to worry or be anxious (μὴ μεριμνήσητε), when they were handed over (ὅταν δὲ παραδῶσιν ὑμᾶς) to these courts or tribunals. They should not worry about how or what they should say (πῶς ἢ τί λαλήσητε). It will be given to them (δοθήσεται γὰρ ὑμῖν) in that hour at that time (ἐν ἐκείνῃ τῇ ὥρᾳ) what they should say (τί λαλήσητε). Luke simply said that they were not to make any preparations for their defense. Would you like to be prepared before you went to court?
