Psalms 121:4

He that keepeth Israel - The Divine Being represents himself as a watchman, who takes care of the city and its inhabitants during the night-watches; and who is never overtaken with slumbering or sleepiness. There is a thought in the Antigone of Sophocles, that seems the counterpart of this of the psalmist,

Ταν σανπ , Ζευπ , δυναμιν τις ανδρωνπ

Ὑπερβασια κατασχοι,Ταν ουθπ ' ὑπνος αἱπ -

ρει ποθπ ' ὁ παντογηρως,Ακαματοι τε θεωνΜηνες;

Antig. ver. 613, Edit. Johnson.
