At the end of Isa 43 the Lord pronounces a heavy word of disaster upon His people for their current disobedience and the necessary and upcoming Babylonian captivity - and then begins 44 with a gloriously prophetic corporate titling of "Jeshurun". It means Upright One. God speaks to His people according to His destiny plan - declaring what He has purposed and will eventually bring about. That's so good and critical to remember - particularly in these most trying days. We are here for divine purpose, and there is a divine reward to the faithful.
