Word Study

In depth

A plain-language study of ísthi — the range of meaning it carries, how Scripture actually uses it, and where it points. Written for readers who don’t know the original language.

Core Meaning & Semantic Range

The Greek word ísthi, represented by G2468, is a direct command as the second person imperative form of the verb "to be." It carries the essential meaning be thou. This term appears 5 times across 5 unique verses in the Bible. While rare, its usage is significant, translating into commands such as agree, be, and give thyself wholly to.

Biblical Occurrences & Contextual Analysis

In scripture, G2468 is used to issue direct and transformative commands from a position of authority. It is used to command a change in relationship, urging a person to agree with an adversary to avoid judgment Matthew 5:25. An angel uses it to command Joseph to find safety in a specific location, saying "be thou there" in Egypt until Herod's threat has passed Matthew 2:13. Jesus uses it to confer a new state of being, such as granting authority to a faithful servant (have thou authority over ten cities) Luke 19:17 and restoring a woman to health by saying "be whole of thy plague" Mark 5:34. It also conveys a call to total dedication, as when believers are told to give thyself wholly to spiritual disciplines 1 Timothy 4:15.

Related Words & Concepts

Several related words help clarify the state or action being commanded by G2468:

  • G1849 exousía (authority): This is the state conferred upon the good servant. The command "be thou" is an instruction to wield authority and delegated influence Luke 19:17.
  • G5199 hygiḗs (healthy): In Mark 5:34, the command is to be whole, which is described by this word meaning healthy, or well in body.
  • G5343 pheúgō (to run away): The instruction to flee into Egypt is immediately followed by the command to "be thou there," contrasting a command of movement with a command of stillness and position Matthew 2:13.
  • G2132 eunoéō (to be well-minded, i.e. reconcile): This word is used with G2468 in Matthew 5:25 to form the compound command to agree with an adversary.

Theological Significance

The theological weight of G2468 lies in its nature as a direct, authoritative command that alters a person's state or responsibility.

  • A Command to Be, Not Just Do: G2468 goes beyond simple action. It commands a state of being, whether it is to be whole Mark 5:34, to be a person with authority Luke 19:17, or to be dedicated 1 Timothy 4:15.
  • Divine Instruction and Authority: The commands are issued by Jesus, an angel of the Lord, or through apostolic instruction. For instance, an angel commands Joseph to "be thou there" to protect the young child Matthew 2:13, and the lord in the parable grants authority to the faithful servant Luke 19:17.
  • Consequential Action: Following the command has critical results. To agree with an adversary prevents being delivered to the judge Matthew 5:25, and to be faithful results in being granted authority Luke 19:17. The command to "be whole" brings an end to suffering Mark 5:34.

Summary

In summary, G2468 is a potent but infrequent imperative that means be thou. Its five appearances in scripture are all direct commands that establish a new reality for the recipient. It is used to confer healing, grant authority, ensure safety, demand reconciliation, and call for complete dedication. Through ísthi, a simple command to "be" becomes a powerful vehicle for divine will, capable of changing a person's condition, role, and relationship in an instant.
