The covenant with Abraham (Lk 1:73-1:73)

“God has remembered

The oath

That he swore

To our ancestor

Abraham.”

 

ὅρκον ὃν ὤμοσεν πρὸς Ἀβραὰμ τὸν πατέρα ἡμῶν, τοῦ δοῦναι ἡμῖν

 

In case there was any doubt about what covenant or agreement Zechariah was talking about, he made it clear, via this canticle in Luke, that this was the covenant or agreement with Abraham to have him and his many descendants be prosperous as in Genesis, chapter 22:16-18.  Zechariah said that God had remembered or given them (τοῦ δοῦναι ἡμῖν) the oath (ὅρκον) that he swore (ὃν ὤμοσεν) to Abraham (πρὸς Ἀβραὰμ), their ancestor or father (τὸν πατέρα ἡμῶν).  The covenant was coming about right before their very eyes.  Notice it was not the Mosaic, but the older Abrahamic covenant that Luke emphasized.

The punishment for Babylon (Jer 51:24-51:24)

“‘I will repay

Babylon

With all the inhabitants

Of Chaldea,

Before your very eyes,

For all the wrong

That they have done

In Zion.’

Says Yahweh.”

Yahweh was simple and direct in this oracle about Babylon. He was going to repay Babylon with the all the Chaldeans for the wrongs that they had done to Zion, Jerusalem. This was going to happen before their very eyes.
