Widespread Sin and the Universal Flood
6:1 Now it came to pass, when man began to multiply on the face of the earth , and daughters were born to them,
6:2 That sons of Elohim (אלהים) saw the daughters of men, that they were beautiful; and they took them wives for themselves of all whom they chose.
6:3 And YHWH (יהוה) said:
"My Ruach shall not strive with man forever, for that he also is indeed flesh: therefore shall his days be One hundred and twenty years.
6:4 There were Nefilim (giants) in the earth in those yamin (days); and also after that, when benai Elohim (אלהים) came in to banot ha adam, and they bare [children] to them, the same [became] mighty men which [were] of old, men of renown.
And YHWH (יהוה) saw (וירא) that the ra'ah (wickednessרעת) of man was [was] great in the earth, and [that] every yetzer (imaginations) of the machshevot (thoughts) of his heart [was] only evil continually.
6:6 Ve yi nakhem (relented, נחם) YHWH (יהוה) that He had made man on the earth, and it grieved Him at His heart.
6:7
וַיֹּאמֶר יְהֹוָה אֶמְחֶה אֶת-הָאָדָם אֲשֶר-בָּרָאתִי מֵעַל פְּנֵיהָאֲדָמָה מֵאָדָם עַד-בְּהֵמָה עַד-רֶמֶשׂ וְעַד-עוֹף הַשָּמָיִם כִּינִחַמְתִּי כִּי עֲשִׂיתִם׃
Vayomer YHWH emcheh et-ha'adam asher-barati me'al penei ha'adamah me'adam ad-behemah ad-remes ve'ad-'of hashamayim ki nichamti ki asitim.
And YHWH (יהוה) said:
"I will machah (wipe out) man whom I have created from the face of ha adamah; both man, and behemah, and the creeping thing, and the fowls of the air; for it relented Me that I have made them.
6:8 וְנֹחַ מָצָא חֵן בְּעֵינֵי יְהֹוָה׃
VeNoach matza chen be'einei YHWH.
But Noach (נח) found favour (חֵן grace chen 蒙恩) in the eyes of YHWH (יהוה).

6:9 (i) Noach and his three sons
אֵלֶּה תּוֹלְדֹת נֹחַ נֹחַ אִיש צַדִּיק תָּמִים הָיָה בְּדֹרֹתָיו אֶת-הָאֱלֹהִים הִתְהַלֶּךְ-נֹחַ׃
Eleh toledot Noach: Noach ish tzadik tamim hayah bedorotav et-ha'Elohim hit'halech-Noach.
These are the genealogies of Noach: Noach was a righteous man, blameless in his
generation. Noach continually walked with Elohim. 
6:10 And Noach (נח) begat three sons, Shem (שׁם), Ham (חם), and Yefet (יפת).
6:11 Vatishakhet haeretz lifnei haElohim vatimale haeretz hamas:
And the earth corrupted itself before Elohim, - and the earth was filled with violencee,
6:12 And Elohim (אלהים) looked upon the earth, and, hinei, it was shachat (corrupt); for all flesh had corrupted his way upon the earth.
6:13
And Elohim (אלהים) said to Noach (נח):
"The end of all flesh is come before Me; for the earth is filled with violence through them; and, hinei, I will destroy them with the earth.
6:14 Aseh lekha tevat atzei-gofer kinim taaseh et-hatevah vekhafarta otah mibayit umikhutz bakofer:
Make yourself an ark of gopherwood; make rooms in the ark, and cover it inside and outside with pitch.
6:15 And this is how you shall make it:
The length of the ark shall be three hundred cubits,
its width fifty cubits, and
its height thirty cubits.
6:16 Make a roof for the ark, and finish it to a cubit above, and set the door of the ark in its side. Make it with lower, second, and third decks.
6:17 For behold, I will bring a flood of waters upon the earth to destroy all flesh in which is the breath of life under heaven. Everything that is on the earth shall die.
6:18 But with you will I establish My Brit; and you shall come into the tevah (ark בּבה), you, and your sons, and your wife, and your sons' wives with you.
6:19 And of every living thing of all flesh, two of every [sort] shall you bring into the tevah (ark בּבה), to keep [them] alive with thee; they shall be zakar (male) and Nekevah (female).
6:20 Of fowls after their kind, and of cattle after their kind, of every creeping thing of the earth after his kind, two of every [sort] shall come to you, to keep [them] alive.
6:21 And take you to you of all oklah (food) that is eaten, and you shall gather [it] to thee; and it shall be for oklah (food) for you, and for them.
6:22 Thus did Noach (נח); according to all that Elohim (אלהים) tzavah (commanded) him, so did he.

The mystery of Genesis 6:1–4
Noah's Ark (Hebrew: תיבת נח, Tevat Noach; Arabic: سفينة نوح, Safina Nuh)
The Ark is 300 cubits long, 50 cubits wide, and 30 cubits high, and it has three decks. Each deck thus has the same height as the Tabernacle and three times the area of the Tabernacle forecourt
k 8:16
The ark is a picture of Mashich. The waters depict Hashem's judgment. Adonay Yeshua went under the waters of divine wrath at Stake. Those who are in Mashaich are saved. Those who are outside are doomed (see Kefa Alef 3:21).
