"Well, that's what father used to call 'em," she laughed. "Of course the Bible didn't name 'em that. But it's all those that begin 'Be glad in the Lord,' or 'Rejoice greatly,' or 'Shout for joy,' and all that, you know--such a lot of 'em. Once, when father felt specially bad, he counted 'em. There were eight hundred of 'em."
"Yes--that told you to rejoice and be glad, you know; that's why father named 'em the 'rejoicing texts.' "
I'm going to look for verses and texts about giving thanks to God.
