Genesis 7

Probably the greatest thing that could be said of man is that said of Noah -
"...Noah did according unto all that the LORD commanded him." (Old Testament | Genesis 7:5)

The would be a great epitaph. For -

"Noah and his sons hearkened unto the Lord, and gave heed, and they were called the sons of God." (Pearl of Great Price | Moses 8:13)

Noah was commanded to preach repentance to the people for the Lord said -

"My Spirit shall not always strive with man, for he shall know that all flesh shall die; yet his days shall be an hundred and twenty years; and if men do not repent, I will send in the floods upon them." (Pearl of Great Price | Moses 8:17)

For a 120 years did Noah preach with no results. I think the warning was sufficient. And then again in obedience, he did -

"Make thee an ark of gopher wood; rooms shalt thou make in the ark, and shalt pitch it within and without with pitch." (Old Testament | Genesis 6:14)

The scriptures do not reflect how long it took him to do so. But the day of warning did arrive -

"And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood." (Old Testament | Genesis 7:7)

What is interesting is, when -

"In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah's wife, and the three wives of his sons with them, into the ark;
14 They, and every beast after his kind, and all the cattle after their kind, and every creeping thing that creepeth upon the earth after his kind, and every fowl after his kind, every bird of every sort.
15 And they went in unto Noah into the ark, two and two of all flesh, wherein is the breath of life.
16 And they that went in, went in male and female of all flesh, as God had commanded him: and the LORD shut him in." (Old Testament | Genesis 7:13 - 16)

The animals followed after Noah and family had entered the ark as the Lord had commanded the animals. The other thing that caught my attention was the flood did not occur just from the rain for -

"...the same day were all the fountains of the great deep broken up..." (Old Testament | Genesis 7:11)

...or as the footnote says - "burst open". Later as the floods ended as -

"the fountains also of the deep and the windows of heaven were stopped..." (Old Testament | Genesis 8:2)

The earth literally was flooded also by water coming out of the ground.
