The following commentary covers Chapters 18, 19, and 20.
In chapters 18, 19 and 20
David, already delivered from all internal conflict in
Israel, triumphs over the heathen, and spreads the glory
of Israel and of his reign on every side. These are the
events which occasioned Psalm 18, although it has a more
extended meaning (compare vers. 36-45).
It will also be remarked
that all David's faults are passed over in silence.
Faithfully recounted elsewhere, they have no place here,
because it is the fulfilment of the ways and thoughts of
God in the house of the elect king that is here depicted.
The children of the giant
fall with the Philistines before the children of Israel.
