In the Bible you'll find passages like -
Exodus 37 Bezalel made the ark of acacia wood—two and a half cubits long, a cubit and a half wide, and a cubit and a half high.[a] 2 He overlaid it with pure gold, both inside and out, and made a gold molding around it. 3 He cast four gold rings for it and fastened them to its four feet, with two rings on one side and two rings on the other. 4 Then he made poles of acacia wood and overlaid them with gold. 5 And he inserted the poles into the rings on the sides of the ark to carry it. 6 He made the atonement cover of pure gold—two and a half cubits long and a cubit and a half wide. 7 Then he made two cherubim out of hammered gold at the ends of the cover. 8 He made one cherub on one end and the second cherub on the other; at the two ends he made them of one piece with the cover. 9 The cherubim had their wings spread upward, overshadowing the cover with them. The cherubim faced each other, looking toward the cover.

My question is why did God choose to include all this information in the Bible? How would the 760 men of Zakkai help anyone in this age or any past or future age, draw closer to God? Contrast this with how small the important narratives like the flood & Noah or the Crucifixion of Christ are.
This doesn't seem like God inspiring the Bible to communicate with men. This seems more like random writings of people about their society and culture put together in one book.
What is the reason for this?
