P
arshas Lech Lecha
“Then Avraham fell upon his face and laughed.” (Bereishis 17:17)
We find the concept of tzechok laughter several times in the Torah.
In parshas Vayeira (18:12) it says: “And Sarah laughed [vatitzchak] within herself.”
Later (21:9) it says about Yishmael: “And Sarah saw the son of Hagar… mocking [metzacheik].”
