curseth
The term {yekallel} signifies not only to curse, but to speak contemptuously, disrespectfully, or to make light of a person: so that all speeches which have a tendency to lessen our parents in the eyes of others, or to render their judgment, piety, etc., suspected or contemptible, is here included; though the act of cursing, or of treating the parent with injurious or opprobrious language, is what is particularly intended. He who conscientiously keeps the fifth commandment, can be in no danger of the judgment here denounced.
