9463. 'And this is the offering which you shall take from them' means that those requirements are altogether indispensable. This is clear from the meaning of 'offering' as requirements, as above in 9459, 9461. The reason why it means that they are altogether indispensable is that the word 'offering' is now used for a third time, and such repetition implies that they are a necessity.

9461. 'You are to take My offering' means the real requirements for worship. This is clear from the meaning of 'offering' as the interior things of worship which were going to be represented, which are the real requirements, dealt with above in 9459.
