1 Samuel 6:11

And they laid the ark of the Lord upon the cart, and the coffer with the mice of gold and the images of their emerods.

Cross-reference

In 1 Samuel 5:9, the tumors were a divine plague; the golden mice and tumor images here are a guilt offering acknowledging that plague.

2 Samuel 6:3 shows David transporting the ark on a new cart — directly mirroring the Philistines' method here.

1 Chronicles 13:7 repeats the same event of carrying the ark on a new cart — identical to the Philistines' action here.

1 Chronicles 15:13-15 prescribes carrying the ark on shoulders by Levites — contrasting the improper cart method used here.
