Matthew 23:21

And who so shall sweare by the Temple, sweareth by it, and by him that dwelleth therein. Matthew 23:21 (KJV)

In Matthew 23, Jesus delivers a series of teachings and warnings to the scribes and Pharisees, denouncing their hypocritical behavior and highlighting their misguided focus on outward religious displays while neglecting the weightier matters of justice, mercy, and faithfulness. In verses 16–22, He addresses the issue of oaths and swearing by the temple. In Jewish culture, taking an oath was considered a solemn declaration with binding authority, but some religious leaders created loopholes that allowed people to make promises without true fulfillment based on what or whom the oath was sworn by.

Jesus states, “And whoso shall swear by the temple, sweareth by it, and by him that dwelleth therein.” He also says, “And whosoever swears by the altar, he swears by it; and whosoever swears by the temple, he swears by it; and whosoever swears by the gold of the temple, he swears by it.” This emphasizes that the temple’s sacredness derives not merely from its physical structure but from God’s presence within it. Any oath invoking the temple inherently invokes God Himself, making such vows weighty and not to be taken lightly.

Jesus further teaches a higher standard of truthfulness, emphasizing that a believer’s “yes” should be yes and their “no” should be no, without the need for elaborate oaths (Matthew 5:33‑37). By linking the oath to the One who dwells in the temple, He underscores that integrity belongs to the heart, not merely to external ritual. The passage therefore calls believers to honor God’s presence in all their commitments, rejecting empty or deceptive practices and embracing sincere, straightforward speech.
