Numbers 13: 31- 34

[31] In the mean time Caleb, to still the murmuring of the people that rose against Moses, said: Let us go up and possess the land, for we shall be able to conquer it. [32] But the others, that had been with him, said: No, we are not able to go up to this people, because they are stronger than we. [33] And they spoke ill of the land, which they had viewed, before the children of Israel, saying: The land which we have viewed, devoureth its inhabitants: the people, that we beheld, are of a tall stature. [34] There we saw certain monsters of the sons of Enac, of the giant kind: in comparison of whom, we seemed like locusts.
[Numbers 13:1-34]

We have a lot of basalt columns in the part of the state where I live. They are quite beautiful, but I do like rocks.

"the vast history of giants has, for the most part, been kept from the public. Proof of giants' existence - their skeletal remains - has been quickly secreted away in obscure museums, when not destroyed. Additionally, time has cloaked and sugar-coated these creatures' true perverse nature, the majority too vile, too demonic for bedtime stories. However, history is replete with their tales of unimaginable cruelty, sɛҳuąƖ perversity, cannibalism and pagan rituals. This is only the beginning. Some things are best forgotten. . . or are they?
Where did these giants come from and what was their connection with ordinary humans? Just who were they? What happened to these extraordinary creatures? Is it possible they could ever return? The last question I will answer right now - YES, they most definitely could return! And they have something much worse in mind for mankind.
