'Someone' in the Bible

Should an axe brag against him who chops with it? Should a saw exalt itself above him who saws with it? As if a rod should lift those who lift it up, or as if a staff should lift up someone who is not wood.

The fading flower of his glorious beauty, which is on the head of the fertile valley, shall be like the first-ripe fig before the summer; which someone picks and eats as soon as he sees it.

Behind the doors and the posts you have set up your memorial: for you have uncovered to someone besides me, and have gone up; you have enlarged your bed, and made you a covenant with them: you loved their bed where you saw it.
