'Part' in the Bible

Every man to whom God has given money and wealth and the power to have pleasure in it and to do his part and have joy in his work: this is given by God.

Their love and their hate and their envy are now ended; and they have no longer a part for ever in anything which is done under the sun.

Have joy with the woman of your love all the days of your foolish life which he gives you under the sun. Because that is your part in life and in your work which you do under the sun.

Give a part to seven or even to eight, because you have no knowledge of the evil which will be on the earth.
