How can you say that the old testament never mentions Jesus by name?

.The ‘old testament’ is the Church version and alas often MIStranslation of the Jewish Tanakh.

Jesus is not mentioned anywhere in the Tanakh.

Jews don’t read or study the OT. I therefore can’t say whether the name ‘Jesus’ appears in it or not – but I gather ‘not’ from what my Christian friends tell me.

Please note:  The Tanakh was a complete ‘bible’ for thousands of years BEFORE Jesus was even born. And the original HEBREW Isaiah says NOTHING about Jesus. Why on earth would it? He’s not part of Judaism and never was.
