rock in Horeb
Exodus 17:6
17:6 rock in Horeb. This is the first mention of “rock” in Scripture, and it is significantly taken by Paul as a type of Christ (see adjacent note). Just as Moses smote the rock with his rod of judgment (Exodus 17:5), so Christ had to be “smitten of God” (Isaiah 53:4) before He could invite men to “come unto me, and drink” (John 7:37).
