What three basic values are emphasized in the ten commandments

Respect - respect for parents, God, neighbors (other humans/friends), God's creation

holiness & faith - reserving Sunday as the Sabbath and day of rest and holiness, only worshipping 1 God

being faithful and conscious - not stealing from others, not committing adultery or coveting good from neighbors
