until he receive the early and latter rain.
(Jewish reference)

the judge standeth before the door.

for an example of suffering affliction, and of patience.

Ye have heard of the patience of Job, and have seen the end of the Lord; that the Lord is very pitiful, and of tender mercy. The 42 chapters of Job is a picture of the 42 months of great tribulation for Israel, aka Jacob's trouble.
