“Give for alms
That are within!
Everything will be clean
πλὴν τὰ ἐνόντα δότε ἐλεημοσύνην, καὶ ἰδοὺ πάντα καθαρὰ ὑμῖν ἐστιν.
Luke uniquely had Jesus turn to alms. The Lord Jesus told the Pharisee that they should give alms (δότε ἐλεημοσύνην) with things that are from within them (λὴν τὰ ἐνόντα), so that everything would be clean for them (καὶ ἰδοὺ πάντα καθαρὰ ὑμῖν ἐστιν). Giving alms would help them, since this was already part of the Mosaic and Pharisaic law, but it had to be interior and and not exterior. It is hard to figure out what an interior almsgiving would be. Are you generous in your gift giving to others?
“God has remembered
That he swore
To our ancestor
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.
