@Hanna_Brassheart @Xonos_Darkgrate1 I believe that the world is round. I would like to present this 16th century voyage as proof. [https://www.history.com/topics/exploration/ferdinand-magellan] Historical evidence. Voila.

While plane evidence could be faked, there's very little arguing with dudes traveling around the world on a BOAT. Their soles of their feet did not leave this planet. Let us walk circumspectly, indeed. (That pun is beautiful.)
But considering the evidence provided by the opposition...
This doesn't tell us that the earth is flat, merely that God will distort its surface, whatever that surface happens to be. The context of this passage is about God's judgement, not about the shape of the earth. See also:
The earth can wither like a fruit...or a pizza...wait the fruit thing makes more sense...anyway. 
I think @Xonos_Darkgrate1 covered this well. Satan has VillainVision (TM). 
Okay, context alert - this is part of a song, most specifically a song of thanksgiving composed by David:
It's pretty evident from the context that "moved" refers to the earth being destroyed outside of God's plan. The larger context is David praising God for the return of the ark to Jerusalem, so we are into poetic license - and clearly David is praising God for establishing the earth, not making a scientific comment on the earth's position.
The only explanation for this is that this passage was written from the perspective of Joshua and the Isrealites. In fact, the context makes it clear that this was written of Joshua's limited scientific knowledge:
This whole passage is written from Joshua's perspective. It even includes a line from Joshua himself in dialogue - he said for the sun to stand still, and from his perspective, that is exactly what happened.
But I see that sense has been ignored thus far, so whatever.
