Asking About 'Son' in the Tanakh

Assalamu alaikum, dear Muslim brothers and sisters. I'm curious about how Islam sees some ideas from the Jewish Tanakh. I know that Muslims believe the original messages to the prophets were true, even if the current texts might have some changes. So I’m asking about the concepts, not claiming the text is flawless. There are two parts from the Tanakh that talk about a 'son.' Can you help me understand them from an Islamic view? Isaiah 9:6–7 says: 'For to us a child is born, to us a son is given; and the government shall be upon his shoulder; and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace. Of the increase of his government and of peace there will be no end, on the throne of David and over his kingdom, to establish it and to uphold it with justice and with righteousness from this time forth and forevermore. The zeal of the Lord of hosts will do this.' Proverbs 30:4 asks: 'Who has ascended to heaven and come down? Who has gathered the wind in his fists? Who has wrapped up the waters in a garment? Who has established all the ends of the earth? What is his name, and what is his son’s name? Surely you know!' How do Muslims interpret this idea of a 'son' here? Jazakum Allahu khairan.
