Ezekiel 20:5

In the day; at the time, the season; it speaks not of that precise portion of hours which make up the natural day, but of the time wherein God began to show them his great mercy. When I chose; it includes mercy without merit in them, and it refers to God's declaring by his kindness to them that he had chosen them; it supposeth the free eternal election, but it expressly refers to a temporal and seasonable selecting them from others; chosen, as Isaiah 14:1; again Deuteronomy 7:6,7: or possibly thus, when I went to make them a choice people by refining them from their dross and idolatries contracted in Egypt, so the word Isaiah 48:10, and selecting them. Israel; not personally considered, but nationally. Lifted up mine hand; either assuring them by oath that he would now make good his promise, and bring them out of bondage; it is the gesture of one that solemnly sweareth, and scriptures frequently mention it, as Ezekiel 20:15 Deuteronomy 32:40: or else, stretched out and made bare my arm, i.e. magnified my power for your deliverance. The seed of the house of Jacob: this explaineth and tells us who Israel was. Made myself known unto them, by the miracles which he wrought; for it is not to be understood of making known or discovering his essence and incomprehensible being. It is not unlikely that many of them either were ignorant or forgot God; now by his wonders wrought for their deliverance he brings them to remember him, and look to him. Moses's question in Exodus 3:13 seems to intimate this ignorance of this people. In the land of Egypt; as this expressly directs us to the place, so it points out the time too when Israel was chosen, selected. When I lifted up mine hand unto them; showed my power in performing my oath and promise in what was now to be done, and assuring them of doing what was further promised by him, and expected by them; and to assure them the more, it is doubled. I am the Lord your God: so Exodus 3:13,16,17. Yours from your progenitors, yours by promise, by covenant, and now am come to be your God by actual and punctual performing my word to you, bringing you out of the land of Egypt by a lifted-up hand and arm.
