The amulets from around 600 BCE are ritual formujlars. It is imposisble to date them more precisely, but of course they tell us that such fragments may go back to early times. But you don't date a text according to the oldest elements but according to the youngest.
If you want to find a muchg more intriguing example, the look for Isa 27:1 and compare it with KTU 1.5:1.1--2. Virtual the same text although divided by perhaps a thousand years. And for this see my "Is the Old Testament Still a Hellenistic Book?" In Ingrid Hjelm and Thomas L. Thompson, Biblical Interpretation Beyond Historicity. Changing Perspectives, 7 (Copenhagen International Seminar, London: Routledge, 2016), pp. 61-75.
