'May' in the Bible

Is there a thing whereof it may be said, See, this is new? It hath been already in the ages which were before us.

For he giveth to a man that is good in his sight wisdom, and knowledge, and joy; but to the sinner he giveth travail to gather and to heap up, that he may give to him that is good in God's sight. This also is vanity and pursuit of the wind.

I said in my heart, It is thus with the children of men, that God may prove them, and that they should see that they themselves are but beasts.

As he came forth from his mother's womb, naked shall he go away again as he came, and shall take nothing of his labour, which he may carry away in his hand.

because the word of a king is power; and who may say unto him, What doest thou?

then I saw that all is the work of God, and that man cannot find out the work that is done under the sun: because however man may labour to seek it out, yet doth he not find it; and even, if a wise man think to know it, he shall not be able to find it out.
