Haggai used the same formula titles for all his oracles. Everyone was to have courage, including Governor Zerubbabel, the high priest Joshua, and all the people of the land. They were to get to work. Yahweh was going to be with them, just as he helped them to come out of Egypt. They were not to be afraid, because he had promised that his Holy Spirit would abide with them.
The literary tone changed, as Yahweh, via Amos, reminded the people of Israel on how he had destroyed the Amorites, the people who lived in the Promise Land before the Israelites arrived. These Amorites or Canaanites were very tall like cedar trees and very strong like oak trees. However, Yahweh completely destroyed them including the fruit of their trees above ground as well as the roots of their trees beneath ground, a complete annihilation. After all, he had brought the Israelites out of Egypt. He had protected them for 40 years, while they were in the wilderness or desert. Finally, Yahweh let the Israelites possess the land of the Amorites.
When Israel was a child, Yahweh loved him. He had called his son out of Egypt. However, the more that he called them, the more that they went from him. They kept sacrificing to the Baals, offering incense to these idols. Yahweh was the one who taught Ephraim how to walk. He took him up in his arms. They did not know that he had healed them. He led them around with cords of human kindness and bands of love. He lifted them up to his cheeks. He bent down to fed them. Now instead of Israel or Ephraim as an unfaithful lover as earlier in this work, Israel and Ephraim have become ungrateful children.
Yahweh was clear. Their ancestors had broken the old covenant when he brought them out of Egypt. He had taken them by the hand to lead them out like a husband helping his wife. Yet they still broke the covenant or alliance with Yahweh.
