21:8 Then the guard cries out:
“On the watchtower, O sovereign master,
I stand all day long;
at my post
I am stationed every night.
27:3 I, the Lord, protect it;
I water it regularly.
I guard it night and day,
so no one can harm it.
52:12 Yet do not depart quickly
or leave in a panic.
For the Lord goes before you;
the God of Israel is your rear guard.
