Introduction — Be Merciful
The halakhah "Be Merciful" is one of the New Testament commands most deeply rooted in the Jewish tradition of covenantal mercy (chesed). The term chesed — covenantal faithfulness, operative love — traverses the entire Tanakh and reaches its densest formulation in the prophet Micah: "To do justice, to love mercy, and to walk humbly with your God" (Mi 6:8). Jesus and the apostles do not present this precept as an optional spiritual ideal but as a binding imperative of the new covenant: the Mishnah describes the world as resting on three pillars, among which acts of mercy (gemilut hasadim) (Mishnah Avot 1:2). The pericope of the unmerciful servant (Mt 18:33) and the word of James — "mercy triumphs over judgment" (Gc 2:13) — reveal the juridical dimension: whoever receives mercy incurs a precise obligation to transmit it.
Imitatio Dei: mercy as a path toward divine likeness
The central command of the Sermon on the Plain — "Be merciful, as your Father is merciful" (Lc 6:36) — structures the entire halakhah "Be Merciful" as imitatio Dei. The Greek term οἰκτίρμων (oiktirmon) denotes visceral mercy, not an outward gesture of courtesy. The formula has direct roots in the Jewish tradition: Psalm 103:8 proclaims that the Lord is "merciful and compassionate, slow to anger and rich in grace" (Sal 103:8). To imitate this divine quality is the fundamental halakhic path of the disciple.
The fifth beatitude reaffirms the same logic: "Blessed are the merciful, for they shall obtain mercy" (Mt 5:7). The Beatitudes are not optional spiritual counsels but makarioi — word-events that create new situations defining the profile of the halakhic disciple. Hillel taught the precondition of the command: "Do not judge your neighbor until you have reached his place" (Mishnah Avot 2:4). One who sees the neighbor from within that person's situation learns the operative compassion the command requires.

Hosea 6:6 as hermeneutical norm: mercy above sacrifice
Jesus cites the prophet Hosea — "I desire mercy and not sacrifice" (Os 6:6) — in two distinct contexts: the meal with tax collectors (Mt 9:13) and the Sabbath controversy (Mt 12:7). The twofold citation is not incidental: Jesus establishes a hermeneutical principle. The Hebrew text of Os 6:6 employs the term חֶסֶד (chesed) — operative covenantal faithfulness — not a mere pietistic sentiment. Knowledge of God (da'at Elohim) and chesed are inseparable within the prophetic horizon: to practice mercy is to know God operatively.
In both episodes mercy functions as a superior norm for the interpretation of halakhah: it prevails over formal ritualism and mechanical application of Sabbath rest. Isaiah had already outlined this order of priority — "Share your bread with the hungry, bring the homeless poor into your house" (Is 58:7) — showing that concrete mercy toward the needy is the sacrifice that counts. This prophetic chain Os→Is→Jesus does not abolish the Torah but brings its deepest orientation to fulfillment.
- Os 6:6 cited twice in Matthew (Mt 9:13; 12:7): hermeneutical principle superior to ritual
- Hebrew chesed (חֶסֶד) = operative covenantal faithfulness, not contingent emotion
- Connection with Is 58:7: true fasting includes concrete action toward the poor
- Structural rabbinic basis: gemilut hasadim third pillar of the world (Mishnah Avot 1:2)
