Midrash su Numeri 7:14

… it is written there “Behold the heaven and the heaven of heavens cannot contain You…” (Melachim I 8:27) and here it is written “…the glory of the Lord filled the Tabernacle.” (Shemot 40:35) R’ Yehoshua of Sachnin said in the name of R’ Levi ‘to what is this likened? To an open cave at the edge of the sea. When the sea storms the cave is filled, but the sea is not reduced. So too, even though it is written that ‘the glory of the Lord filled the Tabernacle’ the upper and lower worlds did not lose anything of the brilliance of the glory of the Holy One, just as it is written “Do I not fill the heavens and the earth? says the Lord.” (Yirmiyahu 23:24) Therefore it is written here ‘And it was’. Just as the Divine Presence was here below at the beginning of the creation of the world but withdrew to above, now it returned to be below as it had been “And it was that on the day that Moses finished…” (Bamidbar 7:1) ... [Another explanation. “And it was that on the day that Moses finished erecting the Mishkan…” (Numbers 7:1)] R’ Simon said: at the time when the Holy One told Israel to erect the Tabernacle, He hinted that when the Tabernacle below is erected, the Tabernacle above is erected, as it says “And it was that on the day that Moses finished…” (ibid.) It does not say ‘erecting the Tabernacle’ but rather ‘erecting this (et) the Tabernacle.’ This refers to the Tabernacle above. The Holy One said: in this world, when the Tabernacle was erected, I commanded Aharon and his sons that they bless you. In the time to come I, in my glory, will bless you. So it is written “May the Lord bless you from Zion, He Who made heaven and earth.” (Psalms 134:3)

Incense is precious to the Holy One, blessed be He,. You know this to be so because David was anxious to burn incense, as it is said: I will offer unto Thee burnt-offerings of fatlings with the sweet smoke of rams; I will offer bullocks with goats (Ps. 66:15). Hence you find that no sacrifices in the entire world were praised as highly as those of the leaders. Why? Because they offered incense prior to making their sacrifices, as Scripture states concerning each of their offerings: One golden pan of ten shekels, full of incense (Num. 7:20), and after that is written: One young bullock, etc. Therefore the Holy One, blessed be He, praised each of their sacrifices. He said: This is the sacrifice of so-and-so, this is the sacrifice of so-and-so, as though saying: “It was pleasing to Him, and He was praising them.” Similarly you find that though Ahaz suspended the study of the Torah and closed the schoolhouses, as it is said: Bind up the testimony, seal the instruction among My disciples (Isa. 8:16), and served idols and did many things to anger the Holy One, blessed be He, when the Holy One, blessed be He, weighed all his deeds, He [simply] said: How can I forgive all this? as it is said: Also they have shut up the doors of the porch, and put out the lamps, and have not burned incense nor offered burnt-offerings in the holy place unto the God of Israel. Therefore, the wrath of the Lord was upon Judah and Jerusalem, and He hath delivered them to be a horror, and astonishment, and a hissing, as you see with your eyes. For lo, our fathers have fallen by the sword, and our sons and our daughters and our wives are in captivity because of all this (II Chron. 29:7–9). What does all this refer to? His failure to burn incense.
