Is Hermeneutics needed? Isn't the Bible self-interpretting?

[Geert van den Bos]

Yes because that spells Ayin Dalet = ED (Witness) to God's Unity.

Deu 5:20 Neither shalt thou bear false witness (ed) against thy neighbour.

And again:

Isa 43:10 Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.

Mark 14:55
οἱ δὲ ἀρχιερεῖς καὶ ὅλον τὸ συνέδριον ἐζήτουν κατὰ τοῦ Ἰησοῦ μαρτυρίαν εἰς τὸ θανατῶσαι αὐτόν, καὶ οὐχ ηὕρισκον·
