The phrase ‘nobody gives it a thought’ is ‘takes to heart’ or sum al lev. Sum means ‘to place or set’ in the sense of directing their attention or putting their mind to.’ Al is a preposition that means ‘upon, above or over.’ Lev means ‘inner man, will, and mind.’ Lev also means ‘thinking or reflecting’ with the soul.
Tzadaqah is the Hebrew word for ‘righteousness’ meaning ‘to be justified, to be loyal, honest, lawful.’ ‘Righteousness’ is found 130 times in the Hebrew Scriptures. Righteousness can simply mean ‘acting rightly before the lawgiver’ in truth and mercy. Melchizedek in Hebrew is Melech Tzadek meaning ‘King of Righteousness.’
Justification is the first step salvation. Justification is just receiving your ‘get out of death row’ card. A repentant individual will appreciate the ‘card’ and the judge who gave it to him freely, and sanctify his lifestyle to one worthy of being set free from the ‘law of sin and death.’
