In Matthew 5:21–26 Jesus outlines his interpretation and application of the sixth command, “Thou shall not murder” (Exod 20:13; Deut 5:17). And though Jesus words are only six verses in length, we can learn at least eleven truths about anger from Christ’s wise words.

Rather, the command to not shed another’s blood is meant to awaken the heart of someone prone to anger. In other words, it is misguided to believe the Lord only cared about the heart in the New Testament.
The Lord has always cared about the heart. Each of the ten commandments were instructed to train the hearts of the Israelites. Deuteronomy 10:16 called upon the Israelites to “circumcise their hearts.” And the common indictment against Israel, under the old covenant, was the problem of their hearts (cf. Isaiah 29:13; Psalm 95).
Hence, Jesus is not giving a new commandment here, but reminding his disciples what the intentions of God were, are, and forever will be. In the law, God called his people to not murder so that it would awaken in them a desire to love, serve, and protect their neighbor.
