Being bound, as in Genesis 42:16, denotes to be separated, for he who is kept bound is separated from the spiritual good, which here is represented by the father Israel.

5452. 'And you will be in bonds' means if all else is separated. This is clear from the meaning of 'being in bonds' here as being separated. For one who is held in bonds is separated, separated from spiritual good meant by their father Israel.
