For the six branches that extend from the lampstand, a calyx must be under the first pair of branches from it, a calyx under the second pair of branches from it, and a calyx under the third pair of branches from it.

For the six branches that extended from it, a calyx was under the first pair of branches from it, a calyx under the second pair of branches from it, and a calyx under the third pair of branches from it.
