shone above the Ark of the Covenant, and the black marks were letters and
the word was the real name of God. She said he was sometimes called
Jehovah, but that was not his real name. His real name was a secret name
which nobody but the High Priest was allowed to say.

When you lay in the dark and shut your eyes tight and waited, you could
see the light, shaped like the vinaigrette, in front of you. It quivered
and shone brighter, and you saw in the middle, first, a dark blue colour,
and then the black marks that were the real name of God. She was glad she
couldn't read it, for she would have been certain to let it out some day
when she wasn't thinking.

Perhaps Mamma knew, and was not allowed to say it. Supposing she forgot?

At church they sang "Praise Him in His name Jah and rejoice before Him."
Jah was God's pet-name, short for Jehovah. It was a silly name--Jah.
Somehow you couldn't help thinking of God as a silly person; he was
always flying into tempers, and he was jealous. He was like Papa. Dank
said Papa was jealous of Mark because Mamma was so fond of him. There was
a picture of God in the night nursery. He had a big flowing beard, and a
very straight nose, like Papa, and he was lying on a sort of sofa that
was a cloud. Little Jesus stood underneath him, between the Virgin Mary
and Joseph, and the Holy Ghost was descending on him in the form of a
dove. His real name was Jesus Christ, but they called him Emmanuel.

"There is a fountain filled with blood
Drawn from Emmanuel's veins;
And sinners plunged beneath that flood
Lose all their guilty stains."
