Albert Barnes Commentary Joshua 5:9

"And Jehovah said unto Joshua, This day have I rolled away the reproach of Egypt from off you. Wherefore the name of that place was called Gilgal, unto this day." — Joshua 5:9 (ASV)

The reproach of Egypt - that is, “reproach proceeding from Egypt.” The expression probably refers to taunts actually uttered by the Egyptians against Israel, because of their long wanderings in the desert and failures to acquire a settlement in Canaan (Numbers 14:13–16; Deuteronomy 9:28; Deuteronomy 32:27). These reproaches were now to end, for they had actually entered Canaan, and the restoration of the covenant was a pledge from God to accomplish what was begun for them.
