"Of course, Jack, if you don't want to, you needn't, and Bumps needn't either, but I'm going to do it. This is going to be a kind of Jacob's pillar. I've been thinking of it a lot, and I'm going to do what Jacob did."
"Run away from home?" asked Jack, his eyes lighting up with eagerness.
"No, of course not. I'm going to give a tenth of my money to God, and I must have a proper place to do it in."
"Oh," said Jack, his face falling a little; "and you want me to do it too."

"I will if Jack does," said Bumps in her breathless way, "I have five pennies!"
"You see me do it first," said Jill; "and then you can make up your mind. It's a very solemn vow, so I must have the stones properly put."
"Yes," said Jack suddenly, "and there was the oil, you know. Jacob had some oil, it's no good without it."
