The number 105 has no prominent or well-established symbolic meaning in biblical or Jewish tradition.
105 is not a number attributed with special symbolism in the Bible or in classical Jewish numerology in a widely recognized way. The number appears in Genesis 5:6, where it states that Seth was 105 years old when he fathered Enosh – one considered among the first to call upon the name of the Lord. Psalm 105 is a well-known hymn of praise recounting God's faithful acts in Israel's history, but the number 105 itself carries no independent symbolic interpretation beyond these contexts. 105 can be decomposed as 3 × 5 × 7, where all three factors are numbers with biblical symbolism (divine perfection, grace, and completion), but the product itself has no established history of interpretation. According to Genesis 4:26, people began to call upon the name of the Lord in the time of Enosh. In rabbinic tradition, there is discussion about whether this marked the beginning of pure worship or the start of idolatry.*
