40 days can mean exactly 40 days. 4 corners
“Not moved” is better translated “not overthrown or destroyed.”

Acts 26:26 for I am persuaded that none of these things are hidden from him; for this thing was not done in a corner.

Corner = location.

Sure it CAN mean exactly 40 days. But would you INSIST upon it? Refuse to consider contradictory evidence against it? Say that anybody who denies that it must be exactly 40 days is compromising scripture?

“Not moved” may well be better translated as “not overthrown or destroyed”, it is certainly consistent with the meaning of the passage (that God made the Earth safe for us). But that has not stopped many from claiming that this passage and others was best interpreted as a Biblical claim for Geocentricity.
