'Weariness' in the Bible

All things are full of weariness beyond uttering. The eye is not satisfied with seeing, nor the ear filled with hearing.

Furthermore, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh.

You say also, 'Behold, what a weariness it is!' and you have sniffed at it," says Yahweh of Armies; "and you have brought that which was taken by violence, the lame, and the sick; thus you bring the offering. Should I accept this at your hand?" says Yahweh.
