H7185 קָשָׁה (qashah): To be hard, severe, or difficult.

These Hebrew terms similarly convey the idea of hardening, whether in a physical, emotional, or spiritual sense, and are often used in contexts where individuals resist God's commands or purposes.

Usage: The verb σκληρύνω is used in the New Testament to describe the act of hardening one's heart or becoming stubborn, particularly in response to God's message or actions.

Context: The term σκληρύνω appears in several key passages in the New Testament, often in the context of spiritual obstinacy or resistance to divine will. It is used both in a literal sense, referring to the physical hardening, and metaphorically, to describe a spiritual or moral hardening of the heart.

In the Book of Acts, σκληρύνω is used to describe the resistance of the Israelites in the wilderness: "But God turned away from them and gave them over to the worship of the host of heaven, as it is written in the book of the prophets: ‘Did you bring Me sacrifices and offerings forty years in the wilderness, O house of Israel?’" (Acts 7:42, BSB). Here, the hardening is a result of turning away from God.

The Apostle Paul uses the term in Romans to explain the spiritual condition of those who reject God's truth: "But because of your hard and unrepentant heart, you are storing up wrath against yourself for the day of wrath, when God’s righteous judgment will be revealed." (Romans 2:5, BSB). This highlights the moral implications of a hardened heart, which leads to judgment.

In Hebrews, σκληρύνω is used as a warning to believers: "Today, if you hear His voice, do not harden your hearts as you did in the rebellion." (Hebrews 3:15, BSB). This serves as an exhortation to remain receptive to God's voice and not fall into the same pattern of disobedience as the Israelites.

The concept of hardening is significant in biblical theology, as it often denotes a deliberate choice to resist God's will, leading to spiritual blindness and separation from God. It serves as a cautionary theme throughout Scripture, urging believers to maintain a soft and responsive heart towards God.
