Isaac; son of Abraham and Sarah. Some passages use Isaac for his descendants rather than the individual. Genesis 17 names Isaac before his birth.

Bearers, aliases and passage context
Isaac; son of Abraham and Sarah. Some passages use Isaac for his descendants rather than the individual.
Genesis 17 names Isaac before his birth. Abraham has just laughed at the prospect of a son in old age. In Genesis 18, Sarah laughs at the same prospect and then denies it. These two scenes make the laughter connection specific; it is not simply a modern description of a happy child.
Genesis 21 returns to the word after Isaac is born. Sarah says that God has made her laugh and that those who hear will laugh with her. Doubt and joy occupy different places in the story. Reducing all three scenes to a single cheerful slogan removes that movement.
The historical dictionaries agree on the short gloss laughter. Their longer articles also offer dates and biographical estimates. This explanation does not adopt those estimates merely because the entry gives the right name gloss. Birth stories, later family events and chronology are separate claims.
Isaac is not an instruction to laugh at suffering or a promise that a person with this name will have an easy future. The account has its own family conflict and later trials. A name gloss tells less than a whole biography, even when the narrative openly plays on that gloss.

FAQ
Why do Abraham and Sarah both laugh?
Genesis places their laughter in separate scenes before Isaac's birth. Genesis 21 then presents Sarah's laughter after the birth. Reading those scenes together shows doubt, surprise and joy in context; the name does not flatten them into one emotion.
