From the New Testament we look back and see that all of it, while applicable to David and the earthly kings who followed, points beyond its original context to Christ, Son of David, who would go forth from heaven, take upon himself flesh and blood, and win the victory for us as the Captain of our salvation.
This is the audio file from the sermon I preached on Sunday, June 19, 2016, at the Winnsboro Reformed Church. I hope it will be a blessing to you.

(To the choirmaster. A Psalm of David.)
May the LORD answer you in the day of trouble!
May the name of the God of Jacob protect you!
May he send you help from the sanctuary
and give you support from Zion!
May he remember all your offerings
and regard with favor your burnt sacrifices! Selah
May he grant you your heart's desire
and fulfill all your plans!
May we shout for joy over your salvation,
and in the name of our God set up our banners!
May the LORD fulfill all your petitions!
Now I know that the LORD saves his anointed;
he will answer him from his holy heaven
with the saving might of his right hand.
Some trust in chariots and some in horses,
but we trust in the name of the LORD our God.
They collapse and fall,
but we rise and stand upright.
O LORD, save the king!
May he answer us when we call.
