1. Cities of refuge (1-14)
Israel had come out of slavery. In a slave society, mistakes and crimes were dealt with according to human passions. God's law established basic justice. Men must know what justice is if they are to appreciate mercy. Six cities were designated 'cities of refuge' (2,9). They were places where a person who accidentally killed another 'without malice aforethought' might flee for safety. He should be protected from the rage of the avenger. On the other hand, one who kills deliberately--in anger or hatred--must be brought to justice. Justice cannot come from anger or passion; revenge has no place in God's justice.
2. Witnesses (15-21)
Truth is established by witnesses; the guilt or innocence of a person is decided on the basis of the testimony of witnesses. A false witness is particularly evil, because he perverts justice. Basic justice--an eye for an eye, a tooth for a tooth--is the foundation on which Jesus built a higher concept of justice, one tempered with mercy and forgiveness.
Application: Lord, thank you for the refuge of the cross. Help me to act justly and love mercy.
One Word: Love God; walk in his ways
