Reading the opening Psalm for today, I was reflecting upon how often the term “my rock” is used.
Psalms 28:1 A Psalm of David. Unto thee will I cry, O LORD my rock; be not silent to me: lest, if thou be silent to me, I become like them that go down into the pit.
In this exact wording 12 times, 9 in Psalms and 3 in Chapter 22 of 2 Samuel.
2Sa 22:2 And he said, The LORD is my rock, and my fortress, and my deliverer;
2Sa 22:3 The God of my rock; in him will I trust: he is my shield, and the horn of my salvation, my high tower, and my refuge, my saviour; thou savest me from violence.
2Sa 22:47 The LORD liveth; and blessed be my rock; and exalted be the God of the rock of my salvation.
Gill writes that these words echo those in the Psalms.
INTRODUCTION TO SECOND SAMUEL 22
This chapter contains a song or psalm, the same with the eighteenth psalm, and which, according to Jarchi, was composed by David in his old age, and, as Kimchi says, at the end or close of his days; but Abarbinel is of opinion that it was written in his youthful time, in the midst of his troubles, and was sung by him as often as he had a deliverance from any; and which may account for the several variations in it from the eighteenth psalm, which, the same writer observes, are seventy four; and are not to be ascribed to the difference of copies, or neglect of copiers: and very probably, towards the close of his days, he revised it, and made it fit for general use, and sent it with the rest of his psalms to the chief musician; but the particular consideration of it, and of the differences in it from Psa 18:1 are referred to the exposition of that book in its course.
