Exodus 6:5,6 - Joseph Benson’s Commentary on the Old and New Testaments

I have heard the groaning of the children of Israel He means their groaning on occasion of the late hardships put upon them. God takes notice of the increase of his people's calamities, and observes how their enemies grow upon them. I will bring you out: I will rid you: I will redeem you: I will bring you into the land of Canaan; and I will give it you Let man take the shame of his unbelief, which needs such repetitions, and let God have the glory of his condescending grace, which gives us such repeated assurances. With a stretched-out arm With almighty power: a metaphor taken from a man that stretches out his arm, to put forth all his strength.
