The Hebrew noun maamatsah refers to a heavy burden or load — the physical or metaphorical weight that weighs a person down. It comes from the root amats (to be strong/burdensome).
Maamatsah appears in Zechariah 12:3, where Jerusalem is described as a 'heavy stone' that will be a burden to all who try to move it — but will wound anyone who tries. This image of the city of God as an immovable, nation-injuring stone finds its New Testament echo in Jesus as the cornerstone that crushes those who fall on it (Matthew 21:44). The word captures the paradox of divine weight: what seems burdensome to human schemes is actually the glory-laden presence of God.
