‏ Genesis 21:6

Summary for Gen 21:6-7: 21:6-7  a Sarah was filled with joy and praise for this amazing event—only God could enable her to have a child. 21:6  b Sarah’s wordplay on the name Isaac (Hebrew yitskhaq, “he laughs”) shows that the laughter of unbelief when the promise was given (18:12  c) had changed to the laughter of joy at its fulfillment. Isaac’s name could refer to the pleasure of God and of his parents at his birth. Sarah knew that everyone who heard about this would laugh with her and rejoice at the news.
