It is now Week 1 of Greek Isaiah in a Year. Here, for ease of reference, is the schedule for this week along with screenshots of the public domain R.R. Ottley text. (Download all of Ottley’s Book of Isaiah According to the Septuagint as a pdf here.) Sunday, December 2 could perhaps be spent reading all of the week’s text one time, then each day could go more in depth.
Monday, December 3: Isaiah 1:1-5
Tuesday, December 4: Isaiah 1:6–10
Wednesday, December 5: Isaiah 1:11–15
Thursday, December 6: Isaiah 1:16–20
Friday, December 7: Isaiah 1:21–25
