Imaginations
Gen 6:5 translated from Hebrew says, the thoughts and intentions of mans’ heart were evil all day long.
The word used in Gen 6:5 is Imagination (H3336 – yēṣer)
The root word for Yeser – imagination is H3335 – yāṣar : which means to squeeze or form into shape.
So YHVH Yasar’d us (Genesis 2:7) – and He gives us instructions and guidelines to help us with our natural sinful pull in our Yeser (thoughts/intentions).
Ark
Gen 6:14 the word for ark, made of gopher wood (which is another rabbit trail..) – is the word H8392 – tēḇâ.
Teba/Ark means like a chest/box/even a coffin.
The ONLY other place where this word is used in Scripture is in Exodus 2:3/5, where Moses was placed in a Ark of bulrushes (cattail wetplants from rivers). In both these cases, 2 great men from our Bible history were saved from the waters, Noah and Moses. And with both these men, YHWH made a covenant with men. One with the Rainbow, and second with the Commandments & Instructions (Torah).
