Study Scripture on a sure foundation.

A quiet Bible reader for Mac, with answers that cite verses, your own books, and your notes beside the text.

Themelios on a Mac: Psalm 23 in the reader, and an answer about God's care that quotes Psalm 23 and John 10:11.
“Therefore everyone who hears these words of Mine and acts on them is like a wise man who built his house on the rock.”

Matthew 7:24 (BSB)

On the rock
“The rain fell, the torrents raged, and the winds blew and beat against that house; yet it did not fall, because its foundation was on the rock.”

Matthew 7:25

On sand
“But everyone who hears these words of Mine and does not act on them is like a foolish man who built his house on sand.”

Matthew 7:26

Themelios (θεμέλιος) means foundation. In verse 25, the house stands because it was founded (τεθεμελίωτο) on the rock, a word from the same root. The app is built to help you hear His words and act on them.
