Isaiah was the 8th-century BC Jewish prophet after whom the Book of Isaiah is named.
Within the text of the Book of Isaiah, Isaiah himself is referred to as "the prophet", but the exact relationship between the Book of Isaiah and any such historical Isaiah is complicated. The traditional view is that all 66 chapters of the book of Isaiah were written by one man, Isaiah, possibly in two periods between 740 BC and c. 686 BC, separated by approximately 15 years, and includes dramatic prophetic declarations of Cyrus the Great in the Bible, acting to restore the nation of Israel from Babylonian captivity. Another widely held view is that parts of the first half of the book (chapters 1-39) originated with the historical prophet, interspersed with prose commentaries written in the time of King Josiah a hundred years later, and that the remainder of the book dates from immediately before and immediately after the end of the exile in Babylon, almost two centuries after the time of the historical prophet.
- He has made everything beautiful in its time. Also He has put eternity in their hearts, except that no one can find out the work that God does from beginning to end. - Ecclesiastes 3:11
9 Let love be genuine; hate what is evil, hold fast to what is good;
10 love one another with mutual affection; outdo one another in showing honor.
11 Do not lag in zeal, be ardent in spirit, serve the Lord.
12 Rejoice in hope, be patient in suffering, persevere in prayer.
13 Contribute to the needs of the saints; extend hospitality to strangers.
