Then spoke Joshua to Yahweh in the day when Yahweh delivered up the Amorites before the children of Israel; and he said in the sight of Israel, Sun, stand you still on Gibeon; You, Moon, in the valley of Aijalon.
The Canaanites regarded the sun and moon as deities. Their control by Yahweh must have deeply impressed Israel’s enemies. [Note: See Robert B. Chisholm Jr., "The Polemic against Baalism in Israel’s Early History and Literature," Bibliotheca Sacra 151:603 (July-September 1994):276-77.] The Book of "Jashar" ("righteous," Joshua 10:13) seems to have been a collection of stories of Israel’s heroes. Some of these stories, if not all of them, were in verse and commemorated God’s great acts for Israel (cf. 2 Samuel 1:18). An additional note that Yahweh fought for Israel (Joshua 10:14) reemphasized God’s initiative for His people in faithfulness to His promises.
