4873. '[And he said'] What is the pledge that I am to give you?' means that which made it certain. This is clear from the meaning of 'the pledge' as that which served to make it a certainty, dealt with immediately above in 4872. This meaning - that which made it certain - is also evident from what follows next regarding the pledge that was given.

4872. 'And she said, If you give me a pledge until you send it' means an acceptance provided it was made a certainty. This is clear from the words above spoken by Tamar, 'What do you give me for coming [in] to me?' which mean a conditional acceptance to become joined, 4870. But now an acceptance provided the same was made a certainty is meant, because the purpose of the pledge was to make certain that what was promised would be given.
