“This is My covenant (brit) between Me and between you and your descendants that you must keep: you must circumcise every male.” (Gen. 17:10)
Simcha Raz recounted the following anecdote in his biography of Rabbi Aryeh Levine (1885-1969), the well-known tzaddik of Jerusalem, who was a devoted friend and disciple of Rav Kook:
In 1936, a year after Rav Kook had departed this world, my uncle had a vivid dream. In the dream, he saw Rav Kook dressed in his finest holiday clothes, walking-stick in hand, ready to leave his house.
“I am in a hurry to attend a brit milah (circumcision ceremony),” Rav Kook explained (in the dream). “It is scheduled for ten o'clock, and there is not much time.”
When my uncle woke up in the morning, he asked his wife to call the late chief rabbi’s family. Was there really a brit milah scheduled for that day?
Rav Kook’s widow answered the call.
“No, there is no brit in our family,” she replied.
“But there is a brit in the family of a very good friend of ours, a friend who is dearer to us than our own relatives. A grandson was born to Reb Aryeh Levine, and the brit is to take place at ten this morning. We are rushing now to get there.”
To my uncle, there was no doubt that the spirit of the chief rabbi would be present at this joyous event. So he hurried off to attend the brit. Reb Aryeh Levine, the proud grandfather, was of course in attendance.
The high point of the ceremony occurred when the baby’s name was announced. The child was named ‘Abraham Isaac’ — the first child in Israel to be named after the late chief rabbi.
