The Jews don’t teach this and it’s “their own practice” as you say.
If they do teach anything of it, succession has more to do with filling a position than laying on of hands.
The semikhah tradition of succession died out in the fourth century, according to the Jews.
But the semikhah was already practiced by the Christians from the Apostles, the way God transferred Authority by succession in the old covenant, is how Authority was transferred in the new Covenant.
“As they ministered to the Lord and fasted, the Holy Spirit said, ‘Now separate to Me Barnabas and Saul for the work to which I have called them.’ Then, having fasted and prayed, and laid hands on them, they sent them away” Acts 13: 2-3
Now look closely.
“Moses spoke to God, saying, "Let God, Source of the breath of all flesh, appoint someone over the community who shall go out before them and come in before them, and who shall take them out and bring them in,
so that Gods community may not be like sheep that have no shepherd." And God answered Moses, "Single out Joshua son of Nun, an inspired man, and lay your hand upon him.”
The formal appointment of Shepherds was done through the Semikhah/ laying on of hands succession.
God says “
Single out Joshua son of Nun” in the Old Covenant.
“ the Holy Spirit said, ‘Now
separate to Me Barnabas and Saul for the work to which I have called them.’” In the New Covenant.
Then in both instances, hands were laid upon them.
See how beautiful God’s inspired Word is, can you see the symmetry between old and new Covenants.
So, Apostolic succession through the laying on of hands is spiritual effect, a gift of God transferred. So that the Church of God will not be like sheep without a Shepherd.
That is why we should only listen to Apostolic Successors in the lineage back to the Apostles.
