“Those of low estate are but a breath.

Those of high estate are a delusion.

In the balances they go up.

They are together

Lighter than a breath.

Put no confidence in extortion.

Set no vain hopes on robbery.

If riches increase,

Do not set your heart on them.”

Suddenly there is a discussion about the relative value of wealth. Those of a low estate are like a breath, while those of a high estate are a delusion. Together they are a mere breath. David then asks them not to extort or rob each other, which seems like a good recommendation. If, however, your riches increased, he did not want them to set their heart on their new found wealth.
