“You have heard

That it was said.

‘You shall love

Your neighbor!

You shall hate

Your enemy!’

But I say to you.

Love your enemies!

Pray for those

Who persecute you!’”

Ἠκούσατε ὅτι ἐρρέθη Ἀγαπήσεις τὸν πλησίον σου καὶ μισήσεις τὸν ἐχθρόν σου.

ἐγὼ δὲ λέγω ὑμῖν, ἀγαπᾶτε τοὺς ἐχθροὺς ὑμῶν καὶ προσεύχεσθε ὑπὲρ τῶν διωκόντων ὑμᾶς·

Luke has something similar to this in chapter 6:33, but Matthew is more forceful here.  Once again, Matthew begins by asking them to recall what they have heard said (Ἠκούσατε ὅτι ἐρρέθη) about loving their neighbors (Ἀγαπήσεις τὸν πλησίον σου), based on the holiness code in Leviticus, chapter 19:18.  However, the next phrase, about hating your enemies (καὶ μισήσεις τὸν ἐχθρόν σου), cannot be found in any Hebrew biblical texts.  However, the reading of the psalms, and the general attitude prior to the exile indicates that the Israelites did not generally wish well on their enemies.  They often asked Yahweh to come and destroy their enemies.  Hate was not encouraged, it was just there.  Then Matthew has this solemn strong announcement from Jesus (ἐγὼ δὲ λέγω ὑμῖν), without ambiguity.  They were to love their enemies (ἀγαπᾶτε τοὺς ἐχθροὺς ὑμῶν) and even pray for those who were persecuting them (καὶ προσεύχεσθε ὑπὲρ τῶν διωκόντων ὑμᾶς).  Perhaps, many of the followers of Jesus at the time of Matthew’s writing were actually being persecuted.  In fact, the Byzantine text added here a couple of phrases to elaborate on this.  These followers of Jesus were asked to bless those cursing them (εὐλογεῖτε τοὺς καταρωμένους ὑμᾶς).  They were to do good to those who were spitefully accusing them, hating them, and persecuting them (καλῶς ποιεῖτε τοῖς μισοῦσιν ὑμᾶς, καὶ προσεύχεσθε ὑπὲρ τῶν ἐπηρεαζόντων ὑμᾶς, καὶ διωκόντων ὑμᾶς).  These early Christians were asked to be generous to their enemies and persecutors.
