Question:

Please can you teach me deep insight about meditating on God's Word and how to meditate

Answer:

"My eyes are awake through the night watches, that I may meditate on Your word" (Psalms 119:148).

The term means nothing more than learning God's word and then thinking about it during the day (or night). David said he used to think about the teachings in the Bible while on guard duty at night -- it helped him stay awake.
