Mutual agreement or consent between parties. Paul instructs married couples in 1 Corinthians 7:5 not to deprive one another sexually 'except perhaps by agreement for a limited time.' The word emphasizes mutual decision-making: both spouses must consent to temporary abstinence for prayer. Unilateral decisions violate the 'one flesh' unity of marriage. Classical uses included musical concord and rhetorical agreement. Paul applies it to marital negotiations, insisting that physical intimacy in marriage is a mutual right requiring joint consent to suspend.
