“And when he was departed thence, he found Jonadab the son of Rechab coming to meet him, and he blessed him. And he said to him: Is thy heart right as my heart is with thy heart? And Jonadab said: It is. If it be, said he, give me thy hand. He gave him his hand. And he lifted him up to him into the chariot,”

“This was also a pious man, and a relative of his. Indeed, his family constantly lived in tents and kept away from drunkenness. The prophet Jeremiah mentions them with praise, and history shows their piety. Therefore king Jehu, as soon as he saw him, blessed him, that is, greeted him. Then he asked, "Is your heart as true to mine as mine is to yours?" When he had answered, "It is," Jehu said to him, "If it is, give me your hand." Then, while he was taking him into his chariot, he said, " 'Come with me and see my zeal for the Lord.' So he had him ride in his chariot." From this it clearly appears that also among the ten tribes there were people endowed with piety, and thanks to them, God, who rules everything with wisdom, tolerated all the others.”

The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
