Study
21 That thou hast slain my children, and delivered them to cause them to pass through the fire for them?
22 If a man shall be found lying with a woman married to a husband, then they shall both of them die, both the man that lay with the woman, and the woman: so shalt thou remove evil from Israel.
'To open,' as in Revelation 9, signifies communication and conjunction.
