Numbers 7:86

The golden spoons [were] twelve, full of incense,.... Which points at the use those spoons or cups were of, namely, to carry incense in them, such as were used on the day of atonement l:

[weighing] ten [shekels] apiece, after the shekel of the sanctuary;

Numbers 7:14;

all the gold of the spoons [was] twenty [shekels]; which amounted to forty nine ounces, five drachms, scruples, and eight gains, worth about seventy five pounds of our money.
