Isaiah 41:10: What Fear Not Really Means
Isaiah 41:10 treats fear less as a word to define than as a power to resist. God tells his chosen servant not to surrender to it and grounds that command in his presence, his help and his grip.
2 Chronicles 20:15–22: The Battle Is God's
Judah was outnumbered and told the battle belonged to Yahweh, not to them. Their part was to fear not, stand, believe, and praise while God acted, and the deliverance came before they saw anything.
