(In Hebrew)
12 וְהָגִיתִי בְכָל־פָּעֳלֶךָ וְּבַעֲלִילֹותֶיךָ 1אָשִׂיחָה
שיח, verb, talk, meditate, speak, complain, pray, commune, muse, declare (12-9).
Having been a Christian for a long while, this verse to me always means I will "think" what God is and has done to me. However, looking back the Hebrew bible, the meaning becomes clear. "Mediate" and "muse" are sharing the same word in this verse. It means much more than simply to think or to consider, but more of something "audible"- our talking, speaking, complaining, praying, communing, and declaring Him.
Praise the Lord! The way to contact God isn't just some thoughts in quietness or wondering in my mind, but to actually have conversations with the Lord. How amazing! This is the way we touch Him and enjoy Him.
