Charles H. Spurgeon on Psalms 78:15

The rocks. They were typical of Christ, 1Co 10:4; who is frequently compared to one for height, strength, and duration, shade, shelter, and protection; and is called the "Rock of Israel, " the "Rock of offence to both houses of Israel, "the "Rock of salvation, "the "Rock of refuge, "the "Rock of strength, "the "Rock that is higher than, "the saints, and on which the church is built, and who is "the shadow of a great rock in a weary land." John Gill.
