Isaac

Chambers's Encyclopaedia, Volume 6: Humber to Malta, p. 228

Isaac, one of the Hebrew patriarchs, the son of Abraham and Sarah, and half-brother of Ishmael. His story in Genesis makes him born when both his parents were advanced in age, and die at Hebron at the age of 180, leaving two sons, Jacob and Esau. The Midrash ascribes to him, in allusion to Gen. xxiv. 63, the institution of the afternoon prayer.
