'Weariness' in the Bible

And further, from these, my son, be warned; the making of many books hath no end, and much study is a weariness of the flesh.

He hath built up against me, And setteth round poverty and weariness.

And ye have said, 'Lo, what a weariness,' And ye have puffed at it, said Jehovah of Hosts, And ye have brought in plunder, And the lame and the sick, And ye have brought in the present! Do I accept it from your hand? said Jehovah.
