Isaiah 52:8 Your watchmen shall lift up their voices, With their voices they shall sing together; For they shall see eye to eye When the LORD brings back Zion.
Ezekiel 33:6-7 But if the watchman sees the sword coming and does not blow the trumpet, and the people are not warned, and the sword comes and takes any person from among them, he is taken away in his iniquity; but his blood I will require at the watchman's hand." "So you, son of man: I have made you a watchman for the house of Israel; therefore you shall hear a word from My mouth and warn them for Me.
