“You have heard
That it was said
To those in ancient times.
‘You shall not murder!’
Whoever murders
Shall be liable
To judgment.”
Ἠκούσατε ὅτι ἐρρέθη τοῖς ἀρχαίοις Οὐ φονεύσεις· ὃς δ’ ἂν φονεύσῃ, ἔνοχος ἔσται τῇ κρίσει.
Next Matthew has Jesus expand on the individual commandments. The first of these was killing or murder. Human life was important, as first outlined in Genesis, chapter 4:1-16, in the Cain and Abel story, as well as in chapter 9:5-6, after the Flood. They already knew this basic commandment, since they had heard what had been told to their ancient ancestors (Ἠκούσατε ὅτι ἐρρέθη τοῖς ἀρχαίοις). This was the simple commandment not to murder or kill anyone (Οὐ φονεύσεις) from the Ten Commandments in Exodus, chapter 20:13 and Deuteronomy, chapter 5:17, as well as in Exodus, chapter 21:12-17, where there was a section on homicide. There were consequences for anyone who murdered someone else (ὃς δ’ ἂν φονεύσῃ). They were responsible for their actions. They were liable to be brought to judgment (ἔνοχος ἔσται τῇ κρίσει). This judgment would be before a Jewish court. There were a series of things that had to be done when a murder occurred, as outlined in Deuteronomy, chapter 21:1-9. The law about murder was fairly clear.
