活动时期西元前8世纪

　　古代以色列先知，《旧约》中的〈以赛亚书〉即以其名命名。据说该书前39章是他所著；其他部分的作者不详。西元前742年左右以赛亚受应召成为先知，当时亚述开始向西扩张，稍后便侵略以色列。与阿摩司同时期，以赛亚揭发了犹太人经济和社会的不公，并敦促他们遵守律法否则将承担取消与上帝约定的风险。他正确的断言以色列北部撒马利亚于西元前722年毁灭，他还宣布亚述人将是行使上帝的惩罚的工具。基督教〈福音书〉引用〈以赛亚书〉比其他先知书多，它的“将刀打成犁头”至今仍为人们所传诵。

　　Prophet of ancient Israel after whom the biblical Book of Isaiah is named. He is believed to have written only some of the book's first 39 chapters； the rest are by one or more unknown authors. Isaiah's call to prophesy came c. 742 BC， when Assyria was beginning the westward expansion that later overran Israel. A contemporary of Amos， Isaiah denounced economic and social injustice among the Israelites and urged them to obey the Law or risk cancellation of God's covenant. He correctly predicted the destruction of Samaria， or northern Israel， in 722 BC， and he declared the Assyrians to be the instrument of God's wrath. The Christian Gospels lean more heavily on the Book of Isaiah than on any other prophetic text， and its “swords-into-plowshares” passage has universal appeal.
