Jesus Songs (Psalm 3): Save Me, O My God
1 O Lord, how many are my foes!
Many are rising against me;
2 many are saying of my soul,
“There is no salvation for him in God.” Selah
3 But you, O Lord, are a shield about me,
my glory, and the lifter of my head.
4 I cried aloud to the Lord,
and he answered me from his holy hill. Selah
5 I lay down and slept;
I woke again, for the Lord sustained me.
6 I will not be afraid of many thousands of people
who have set themselves against me all around.
7 Arise, O Lord!
Save me, O my God!
For you strike all my enemies on the cheek;
you break the teeth of the wicked.
8 Salvation belongs to the Lord;
your blessing be on your people! Selah
“A Psalm of David when he fled from Absalom his Son.” You will remember the sad story of David’s flight from his own palace, when, in the dead of the night, he forded the brook Kedron, and went with a few faithful followers to hide himself for awhile from the fury of his rebellious son. Remember that David in this was a type of the Lord Jesus Christ. He, too, fled; he, too, passed over the brook Kedron when his own people were in rebellion against him, and with a feeble band of followers he went to the garden of Gethsemane. He, too, drank of the brook by the way, and therefore doth he lift up the head. By very many expositors this is entitled The Morning Hymn. May we ever wake with holy confidence in our hearts, and a song upon our lips!
Division.—This Psalm may be divided into four parts of two verses each. Indeed, many of the Psalms cannot be well understood unless we attentively regard the parts into which they are to be divided. They are not continuous descriptions of one scene, but a set of pictures of many kindred subjects. As in our modern sermons, we divide our discourse into different heads, so it is in these Psalms. There is always unity, but it is the unity of a bundle of arrows, and not of a single solitary shaft. Let us now look at the Psalm before us. In the first two verses you have David making a complaint to God concerning his enemies; he then declares his confidence in the Lord (3, 4), sings of his safety in sleep (5, 6), and strengthens himself for future conflict (7. 8).
