When you refer to "the early church fathers" the ones I know about helped to bury the Gospel in made up dogma. Again, the Christians who meditate are doing what? Are they developing a personal relationship with Jesus or as the joke goes are they simply focusing on their navels?
Psalm 1:2 - "Blessed is the man who does not walk in the counsel of the wicked, or set foot on the path of sinners, or sit in the seat of mockers. 2But his delight is in the Law of the LORD, and on His law he meditates day and night."
From a quick search in AI Overview is this that might be of interest:
The Hebrew words for "meditate" in the Old Testament are "hagah" and "siyach":
Hagah: A common word translated as "meditate" in the Old Testament. It can also be translated as "growl". In Joshua 1:8, God tells Joshua to "meditate" on his law day and night using the word "hagah". The word "hagah" can also mean "to murmur" or "to ponder". Some say that "hagah" conveys the idea of feeding on God's word with the same passion as a lion eating its prey.
Siyach: Means "to ponder," "to converse," or "to utter".
