'Foundation' in the Bible

They are like a person building a house, who dug a deep hole to lay the foundation on rock. When a flood came, the floodwaters pushed against that house but couldn't shake it, because it had been founded on the rock.

But the person who hears what I say but doesn't act on it is like someone who built a house on the ground without any foundation. When the floodwaters pushed against it, that house quickly collapsed, and the resulting destruction of that house was extensive."

so those living today will be charged with the blood of all the prophets that was shed since the foundation of the world,

Otherwise, if he lays a foundation and can't finish the building, everyone who watches will begin to ridicule him
