Then the LORD said to Abram, “You can be sure that your descendants will be strangers in a foreign land, where they will be oppressed as slaves for...... "400 years."
After...…. "four generations"... your descendants will return here to this land...….(Genesis 15:13,16)
1948 Israel back in the land - plus 100 years = 2048
I tell you the truth, this generation will not pass from the scene until all these things have taken place. - Jesus (Luke 21:32)
