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 σαν, Ζευ, δυναμιν τις ανδρων

Ὑπερβασια κατασχοι,

Ταν ουθ' ὑπνος αἱ -

ρει ποθ' ὁ παντογηρως,

Ακαματοι τε θεων

Μηνες;

Antig. ver. 613, Edit. Johnson.

Shall men below control great Jove above,Whose eyes by all-subduing sleep

Are never closed, as feeble mortals' are;But still their watchful vigil keep

Through the long circle of th' eternal year?

Franklin.

Behold, he that keepeth Israel - The Keeper - the Guardian - of his people. The psalmist here passes from his own particular case to a general truth - a truth to him full of consolation. It is, that the people of God must always be safe; that their great Guardian never slumbers; and that he, as one of his people, might, therefore, confidently look for his protecting care.

Shall neither slumber nor sleep - Never slumbers, never ceases to be watchful. Man sleeps; a sentinel may slumber on his post, by inattention, by long-continued wakefulness, or by weariness; a pilot may slumber at the helm; even a mother may fall asleep by the side of the sick child; but God is never exhausted, is never weary, is never inattentive. He never closes his eyes on the condition of his people, on the needs of the world.
