'Heavy' in the Bible

There were also others who were saying, “We have borrowed money on our fields and vineyards for the [Persian] king’s [heavy] tax.

Now the following were prepared for each day: one ox and six choice sheep; also fowls (poultry) were prepared for me; and in intervals of ten days all sorts of wine was provided in abundance. Yet for all this, I did not demand the governor’s food allowance, because the servitude was heavy on this people.
