Honoring parents involves high esteem, reverence and help. It means being there to look after them, take care of them. Compared to the other commandments, where no specific promise is directly attached, God, in giving this commandment also added a certain promise. He said: "Honor your father and your mother, that your days may lengthen in the land that the Lord your God gives you." But it did not end there. In Deuteronomy 5:16 the same commandment comes but with an additional promise attached:

Deuteronomy 5:16
"Honor your father and your mother, as the LORD your God has commanded you, that your days may be long, and that it may go well with you in the land which the LORD your God is giving you."
