'Ground' in the Bible

(Now they were saying this to test him, so that they would have [an occasion] to bring charges against him.) But Jesus, bending down, began to write with [his] finger on the ground, taking no notice.

And bending down again, he wrote on the ground.

[When he] had said these [things], he spat on the ground and made clay with the saliva, and smeared the clay on his eyes.

So when he said to them, "I am [he]," {they drew back} and fell to the ground.
