C. F. Keil and Franz Delitzsch on Exodus 39:43

Exo 39:43

When Moses had received and examined all the different articles, and found that everything was made according to the directions of Jehovah, he blessed the children of Israel. The readiness and liberality with which the people had presented the gifts required for this work, and the zeal which they had shown in executing the whole of the work in rather less than half a year (see at Exo 40:17), were most cheering signs of the willingness of the Israelites to serve the Lord, for which they could not fail to receive the blessing of God. Call of Moses, and His Return to Egypt - Exodus 3 And 4

Call of Moses. - Whilst the children of Israel were groaning under the oppression of Egypt, God had already prepared the way for their deliverance, and had not only chosen Moses to be the saviour of His people, but had trained him for the execution of His designs.
