Deuteronomy — Chapter 23

An eunuch whose testicles are broken or cut away, or his privy member cut off, shall not enter into the church of the Lord. Lapide explains: 'Church of the Lord' here means the civic assembly of Israel—the right to be counted among the chosen people with its legal privileges—not exclusion from faith, worship, or salvation. Proselytes could still participate in the sacred rites (cf. Ex. 12:48). Allegorically (Theodoret, q. 26): the eunuch signifies sterility of soul, the bastard its evil fruits—both to be kept from the assembly of God.

Thou shalt not lend to thy brother money to usury, nor corn, nor any other thing. The prohibition of usury (lending at interest) among brethren reflects the law of charity: a brother's need is not to be exploited for profit. Lapide notes that 'lend' (foenerare) here means to give mutuum, not to charge usury, as is clear from context.
