“Then his lord

Summoned him.

He said to him.

‘You wicked slave!

I forgave you

All that debt

Because you pleaded with me.

Should not you

Have had mercy

On your fellow slave,

As I had mercy on you?’

In anger,

His lord handed him over

To be tortured

Until he would pay

His entire debt.”

τότε προσκαλεσάμενος αὐτὸν ὁ κύριος αὐτοῦ λέγει αὐτῷ Δοῦλε πονηρέ, πᾶσαν τὴν ὀφειλὴν ἐκείνην ἀφῆκά σοι, ἐπεὶ παρεκάλεσάς με·

οὐκ ἔδει καὶ σὲ ἐλεῆσαι τὸν σύνδουλόν σου, ὡς κἀγὼ σὲ ἠλέησα;

καὶ ὀργισθεὶς ὁ κύριος αὐτοῦ παρέδωκεν αὐτὸν τοῖς βασανισταῖς ἕως οὗ ἀποδῷ πᾶν τὸ ὀφειλόμενον αὐτῷ.

This parable about the unforgiving servant slave is unique to Matthew.  This forgiving lord king summoned his unforgiving slave (τότε προσκαλεσάμενος αὐτὸν ὁ κύριος).  He called him a wicked or evil slave (αὐτοῦ λέγει αὐτῷ Δοῦλε πονηρέ).  The king reminded him that he had forgiven all his debt (πᾶσαν τὴν ὀφειλὴν ἐκείνην ἀφῆκά σοι) because he had begged or pleaded with him (ἐπεὶ παρεκάλεσάς με).  Why did he not show the same mercy to his fellow slave that he had shown to him (οὐκ ἔδει καὶ σὲ ἐλεῆσαι τὸν σύνδουλόν σου, ὡς κἀγὼ σὲ ἠλέησα)?  Then the angry king and lord ordered him handed him over to a torturing jailer (καὶ ὀργισθεὶς ὁ κύριος αὐτοῦ παρέδωκεν αὐτὸν τοῖς βασανισταῖς) until he would pay off his entire debt (ἕως οὗ ἀποδῷ πᾶν τὸ ὀφειλόμενον αὐτῷ).  He could never pay off his enormous debt, so that he would be tortured every day of his life instead of originally being sold with all his possessions, as was the original punishment.  He just had too much debt.  With a little mercy, he would have been okay.
