ὀρθός

upright, straight

Definition

The adjective ὀρθός primarily means 'straight' in a physical or literal sense, as seen in Hebrews 12:13, where it refers to making 'straight paths' for one's feet. It also carries the metaphorical meaning of 'upright' or 'correct,' implying moral or spiritual rectitude. In Acts 14:10, it describes a lame man's feet and ankles being made 'straight' or sound, a healing that symbolizes restoration to proper function. Thus, the word bridges concepts of physical alignment and ethical correctness.

Biblical Usage

This word is used only twice in the New Testament. In Acts 14:10, it describes a physical healing where a lame man's limbs are made 'straight.' In Hebrews 12:13, it is used metaphorically in the exhortation to 'make straight paths for your feet,' urging believers toward a life of moral and spiritual stability that avoids causing others to stumble. Both uses imply a movement from a crooked or impaired state to one of proper order and function.

Etymology

Derived from the Proto-Indo-European root *h₃erdʰ-, meaning 'to grow, to rise.' It is related to the Greek verb ὀρθόω (orthoō, G3717 - to make straight) and is the root for English words like 'orthodox' (correct belief) and 'orthopedic' (straightening of children). Its core idea is that of being set right, aligned, or erect.

Semantic Range

ὀρθός connects physical healing with spiritual and ethical instruction. In Acts 14:10, the miraculous straightening of limbs points to God's power to restore creation. In Hebrews 12:13, the call to make 'straight paths' is part of sanctification, emphasizing that a righteous life is one directed rightly toward God and considerate of fellow believers. Understanding this word enriches reading by showing how biblical imagery uses physical straightness to picture spiritual health and communal responsibility.

In the Greco-Roman world, straight roads and paths were symbols of safety, directness, and good order, contrasting with dangerous, winding trails. The concept of moral 'uprightness' was also a common virtue. The biblical use taps into this cultural appreciation for literal and figurative straightness, investing it with theological significance about divine restoration and holy living.

εὐθύς (euthys, G2117) — emphasizes directness or immediacy ('straightway'), often of time or direction, whereas ὀρθός focuses more on correct alignment. δίκαιος (dikaios, G1342) — focuses on righteousness and justice in a legal or moral sense, while ὀρθός can include physical straightness.
