Commentary for Bava Metzia 3:3
היו שנים רוכבין על גבי בהמה או שהיה אחד רוכב ואחד מנהיג זה אומר כולה שלי וזה אומר כולה שלי זה ישבע שאין לו בה פחות מחציה וזה ישבע שאין לו בה פחות מחציה ויחלוקו
<b><i>GEMARA</i></b>. What need is there [for the Mishnah] to [give two pleas of the litigants and] state: ONE OF THEM SAYS, 'I FOUND IT', AND THE OTHER SAYS, 'I FOUND IT', ONE OF THEM SAYS, 'IT IS ALL MINE', AND THE OTHER SAYS, 'IT IS ALL MINE'? Surely one plea would have been sufficient! — It is only one plea: One says 'I found it and [therefore] it is all mine', and the other says 'I found it, and [therefore] it is all mine'! But why not just state 'I found it', and it will be understood that the intention is to claim the whole garment? — The term 'I FOUND IT' might have been explained as denoting 'I saw it', the mere seeing [of the garment] entitling him to claim it as his possession.<span class="x" onmousemove="('comment',' Though the other man has taken hold of it first.
