Matthew 5:22

Angry with his brother; in his heart, to which God looks.

Without a cause; not merely without an occasion, but rather, in an unreasonable degree, or with any mixture of malice.

The judgment; the judgment of God. The Saviour's meaning is this: by the law of Moses literal murder is punished with death by common court; but in my kingdom anger in the heart will be regarded and treated as murder.

Raca; vain fellow; blockhead. The Saviour puts a case where anger vents itself in railing.

The council; the Sanhedrim, which was the highest Jewish court; but here it seems to represent the court of Christ, who will treat all railing accusations of one brother against another as offences of the gravest kind.

Fool; vile wretch; the highest form of reproach in the mouth of a Jew. A disposition rightly to treat men is essential to acceptance with God.
