OT in Christ's Passion, part 2

"Let this cup pass from Me" - Matt 26:39.
"If this cup cannot pass away from Me unless I drink it..." - Matt 26:42

This passage is greatly enhanced by reading Isaiah 51:17-22, below.

Notice vss 17 and 22 both refer to drinking the cup, and it is the cup of God's wrath in punishment on Israel. But in vs 17 they have drunk and drained it. In vs 22, God takes the cup away, so they don't have to drink it. So Jesus prays for the 2nd option. But that option is only available to Israel as Jesus drinks/takes God's fury at Gethsemane/Golgotha.

And in between Isa 51:17 and 22, a description of Jerusalem in 70AD, when God makes Israel drink His fury for failing to believe in the One who drinks the cup. Verse 18 describes Israel without a Savior - what would have happened if He hadn't drunk the cup of God's wrath on the Cross.

"Awake, awake!
Stand up, O Jerusalem,
You who have drunk at the hand of the Lord
The cup of His fury;
You have drunk the dregs of the cup of trembling,
And drained it out.
18 There is no one to guide her
Among all the sons she has brought forth;
Nor is there any who takes her by the hand
Among all the sons she has brought up.
19 These two things have come to you;
Who will be sorry for you?—
Desolation and destruction, famine and sword—
By whom will I comfort you?
20 Your sons have fainted,
They lie at the head of all the streets,
Like an antelope in a net;
They are full of the fury of the Lord,
The rebuke of your God.

21 Therefore please hear this, you afflicted,
And drunk but not with wine.
22 Thus says your Lord,
The Lord and your God,
Who pleads the cause of His people:
“See, I have taken out of your hand
The cup of trembling,
The dregs of the cup of My fury;
You shall no longer drink it."
