Sforno on Genesis 43:10/ספורנו על בראשית מ״ג:י׳

1כי לולא התמהמנו, the reason I volunteered to consider myself as having sinned against you forever if I fail to bring back Binyamin is only because it is absolutely clear to me that if we had not procrastinated ever since we told you what the man had said to us, or since we ran out of food,

2כי עתה שבנו זה פעמים, we could have been back already twice for the man would not have detained us at all, seeing that he described himself as G’d-fearing. He would not continue to harass us once he realised that we had told him the truth.
