From the early Church Fathers to now.
“But as for you, O mountains of Israel, shoot ye forth your branches, and yield your fruit to my people of Israel: for they are at hand to come.”
“In case this seems to be difficult I will come to you; I who have turned away from you will turn my face toward you, so that you may have the cultivation that you once had and that everything may be filled with seed. In this way there will be many people among you, and the cities that were once destroyed will be inhabited once again.”
“We say that the mountains of Israel, the prophets and the apostles, are those who hear the Word of God and are those to whom the devil is an enemy and against whom he scoffs.”
“I will strengthen the people's hope, and I will make steadfast their expectation of good things to come, and they will return and enjoy those fruits that are produced by you.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
