Now an omer is the tenth part of an ephah.
An omer of manna laid up in a golden pot before the ark was a standing miracle, meant to silence every murmur. Posterity would see what sort of food sustained them, and judge whether they had cause to complain or reason to thank God; eaten bread must not be forgotten. The manna never failed them forty years, though Israel was provoking, thus God's providence is constant, and Christ Himself is the true manna, the bread of life.

Commenting on Exodus 16:32-36
Now an omer [is] the tenth [part] of an ephah. (q) Which measure contained about five gallons.
An omer is roughly six pints English measure, though I confess this verse sits oddly here and belongs better after verse eighteen. The great miracle stands firm: God fed Israel from heaven when they must otherwise have perished, just as Christ came down from heaven for the life of the world. God provided the manna; they gathered it. Neither could do the other's work, and so in both spiritual and temporal things we must be workers together with Him.
