The citation from Hosea about mercy (Mt 9:13-9:13)

“Go!

Learn what this means!

‘I desire mercy,

Not sacrifice!

I have come

Not to call the righteous,

But sinners.’”

 

πορευθέντες δὲ μάθετε τί ἐστιν Ἔλεος θέλω καὶ οὐ θυσίαν· οὐ γὰρ ἦλθον καλέσαι δικαίους ἀλλὰ ἁμαρτωλούς.

 

This response of Jesus is almost the same as in Mark, chapter 2:17, and Luke, chapter 5;31.  Jesus explained that they ought to learn what he means (πορευθέντες δὲ μάθετε), because he desired mercy (τί ἐστιν Ἔλεος θέλω), and not sacrifices (καὶ οὐ θυσίαν).  This was based on Hosea, chapter 6:6, where the essential message was that Yahweh wanted real faithful love, not mere sacrifices.  Hosea wanted the Israelites to have real knowledge of God, rather than worry about burnt offerings.  Jesus had come not to call the people who were righteous already (γὰρ ἦλθον καλέσαι δικαίους), but to call the sinners (ἀλλὰ ἁμαρτωλούς).
