Matthew Henry, Commentary on the Whole Bible… (1700s)
“ It forbids spiritual wickedness, heart-murder, and heart-adultery. It commands spiritual service, requires the heart, obliges us to worship God in the spirit. It is a spiritual law, for it is given by God, who is a Spirit and the Father of spirits; it is given to man, whose principal part is spiritual; the soul is the best part, and the leading part of the man, and therefore the law to the man must needs be a law to the soul. ”
