“On that day,
I will cause
A horn
To spout up
For the house
Of Israel.
I will open
Your lips
Among them.
Then they will know
That I am Yahweh.”
On the day that Yahweh would choose, the horn of David would spring up again in the house of Israel. He was going to open up their lips so that they would know that he was Yahweh, their God. Thus Israel would be restored to its Davidic kingdom glory.
