Corresponding Greek / Hebrew Entries: While there is no direct Hebrew equivalent for ζεστός, the concept of fervency or zeal can be related to Hebrew words such as קָנָא (qanah, Strong's 7065), which means "to be zealous" or "to be jealous," and חָם (cham, Strong's 2525), which means "warm" or "hot." These terms capture similar ideas of intensity and passion found in the Greek ζεστός.

Usage: The term ζεστός appears in the New Testament in contexts that describe temperature, both literal and metaphorical. It is used to convey the idea of being fervent or zealous in spirit.

Context: The Greek word ζεστός is found in the New Testament in Revelation 3:15-16, where it is used in the message to the church in Laodicea. The passage reads: "I know your deeds; you are neither cold nor hot. How I wish you were one or the other! So because you are lukewarm—neither hot nor cold—I am about to vomit you out of My mouth" (BSB). In this context, ζεστός is used metaphorically to describe spiritual fervor and zeal. The Laodicean church is criticized for being lukewarm, implying a lack of commitment or passion in their faith. The use of ζεστός here contrasts with "cold" (ψυχρός, psychros) and highlights the expectation of fervency in one's spiritual life. The imagery of temperature serves as a powerful metaphor for the spiritual state of the believers, urging them to be zealous and committed in their faith.
