Genesis 6:16

16 A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; with lower, second, and third stories shalt thou make it.

Generations later, King David wanted to build a house for the Lord in Jerusalem—a magnificent Temple on Mount Moriah. This temple was actually constructed by his son King Solomon.  At the dedication service, the Lord’s house “was filled with a cloud, so that the priests could not continue ministering because of the cloud; for "the glory of the LORD filled the house of God” (2 Chr. 5:13–14) - This Tabernacle was erected in order that the Shekinah might dwell on earth (Num. R. xii. &Sanh. 103b)  

According to tradition, the Toshar rested between the wings of the seraphim above the Ark of the Covenant...

 The word shekinah means “the dwelling,” a term used throughout Scripture to describe God’s presence with His people (Ex. 25:8; 1 Ki. 6:13). The Shekinah Glory was the literal, physical manifestation of God dwelling among the Jewish nation prior to the coming of the Messiah. Twelfth-century Jewish philosopher Maimonides believed the Shekinah was “a distinct entity” from God, “a light created to be an intermediary between God and the world.” 

The term "Shekinah," which is Hebrew, whereas "Memra" and "Yeḳara" are Aramaic, took the place of the latter two in Talmudand Midrash, and thus absorbed the meaning which they have in the Targum, where they almost exclusively occur. Since the Shekinah is light, those passages of the Apocrypha and New Testament which mention radiance, and in which the Greek text reads δόξα, refer to the Shekinah, there being no other Greek equivalent for the word

Solomon wrote, "...there is no new thing under the sun. Is there anything whereof it may be said, See, this is new? it hath been already of old time which was before us." (Eccl. 1:9-10.)

"According to Jewish myth [the original light] was a primordial light through which Adam could see from one end of the world to another. (PolPovuh! Mayans also teach this!) When Adam and Eve were sent out of the Garden of Eden, God preserved a small part of this light in a stone so that Adam could take it with him. This stone was called the Tsohar and was passed down from prophet to prophet. According to the legend Adam gave it to Seth, Seth gave it to Enoch who gave it to Methuselah who slept next to it. This is why, some say, he lived to such an old age. Methuselah gave it to Lamech who gave it to Noah who hung it in his Ark." -  

“…this ancient Hebrew tradition says the tsohar was a very large pearl or gem that Noah hung in the rafters of the Ark, which powered itself and illuminated the Ark. https://arkencounter.com/blog/2012/09/07/when-is-a-window-not-a-window/

Notes:

The Talmud. Ab. R. N. xxxviii. says: "The Shekinah descended to earth, or will have descended, ten times (as to the tenth see Schechter's note, Recension A, ad loc.): 

1. to the garden of Eden (Gen. iii. 8); 

2. when the Tower of Babel was built (ib. xi. 5); 

3. to Sodom (ib. xxi.); 

4. in the burning bush (Ex. R. ii.)

5. to Egypt (Ex. iii. 8); 

6. to the Red Sea (II Sam. xxii. 10); 

7. upon Sinai (Ex. xix. 10); 

8. in the pillar of cloud (Num. xi. 25); 

9. to the Sanctuary (Ezek. xliv. 2); 

...and that it will again appear at the time of Gog and Magog (Zech. xiv. 4).
