'Severe' in the Bible

There is a grievous evil which I have seen under the sun: riches being kept and hoarded by their owner to his own misery.

This also is a grievous evil—exactly as he was born, so he shall die. So what advantage has he who labors for the wind?

a man to whom God has given riches and wealth and honor so that his soul lacks nothing of all that he desires; yet God has not empowered him to eat from them, for a foreigner enjoys them. This is vanity and a severe affliction.

For there is a proper time and procedure for every matter, for the oppression of the king is severe upon his victim.
