Lilies from the pillars of Jachin and Boaz

KJV:
And he set up the pillars in the porch of the temple: and he set up the right  pillar, and called the name thereof Jachin: and he set up the left pillar, and he called the name thereof Boaz.  And upon the top of the pillars [was] lily work: so was the work of the pillars finished.

NASB:
Thus he set up the pillars at the porch of the nave; and he set up the right pillar and named it Jachin, and he set up the left pillar and named it Boaz.  On the top of the pillars was lily design. So the work of the pillars was finished.

(1 Kings 7:21,22)

First, why are there no such pillars in the Third Temple?

The short answer is: because there is no mention of such pillars in the prophecy of Ezekiel.

The detailed answer: because "two witnesses" have now become one –

KJV:
Say unto them, Thus saith the Lord GOD; Behold, I will take the stick of Joseph, which [is] in the hand of Ephraim, and the tribes of Israel his fellows, and will put them with him, [even] with the stick of Judah, and make them one stick, and they shall be one in mine hand.

NASB:
say to them, 'Thus says the Lord GOD, "Behold, I will take the stick of Joseph, which is in the hand of Ephraim, and the tribes of Israel, his companions; and I will put them with it, with the stick of Judah, and make them one stick, and they will be one in My hand."'

(Ezekiel 37:19)

In other words, the remnant of the Jews and the remnant of Christians will unite into one people, whose name is Israel. I have already mentioned why there will be 24 dining rooms for Israelis: 12 for Israel on earth and 12 for the "heavenly" Israel.

KJV:
 <...> for to make in himself of twain one new man, [so] making peace;

NASB:
<...> so that in Himself He might make the two into one new man, thus establishing peace,

(Ephesians 2:15)

The two pillars that stood before the First Temple now moved inward and became the ends of the wall of the "tabernacle," more precisely, the ends of the wall of the porch, which has a common wall with the wall that surrounds the Holy of Holies. And the lilies that were at the top of the former pillars have now become alive and have filled that part of the inner court  where people do not have to walk.
