'Soil' in the Bible

Others fell on rocky ground, where there wasn’t much soil, and they sprang up quickly since the soil wasn’t deep.

But other seeds fell on good soil and produced a crop, some 100, some 60, and some 30 times what was sown.

The one on whom seed was sown on rocky ground, this is the one who hears the word and at once welcomes it with joy;

But as for what was sown on good soil, this is the person who hears the word, understands it, and produces a crop that yields 100, 60, or 30 times what was sown."
