Does the Bible teach that life begins at conception?

Does the Bible teach that life begins at conception?: God reveals to us in His Word that not only does life begin at conception, but He knows who we are even before then (Jeremiah 1:5). King David said this about God's role in our conception: 'For you created my inmost being; you knit me together in my mother's womb . . . your eyes saw my unformed body. All the days ordained for me were written in your book before one of them came to be.' (Psalm 139:13, 16).
