Ecclesiastes 1:13

"I have seen the travail, which God hath given to the sons of men to be exercised in it."

"In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return."

"Meditate upon these things; give thyself wholly to them; that thy profiting may appear to all."

"And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit."

"And further, by these, my son, be admonished: of making many books there is no end; and much study is a weariness of the flesh."

"I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness: I applied...: Heb. I and mine heart compassed"

"Through desire a man, having separated himself, seeketh and intermeddleth with all wisdom. Through...: or, He that separateth himself seeketh according to his desire, and intermeddleth in every business"

"The works of the LORD are great, sought out of all them that have pleasure therein."

"Wisdom is the principal thing; therefore get wisdom: and with all thy getting get understanding."
