Jerome of Stridon
I beheld a hand that was sent to me. The LXX, rather than referring to it simply as a hand, uses the term outstretched. It echoes the sentiments expressed by the prophet when he asks, 'Has the arm of the Lord been shortened?' (Isaiah 50:2). In the Psalms, it is said, 'Why dost Thou withdraw Thy hand and Thy right hand from the midst of Thy bowels to the end?' (Psalm 73:11). Ultimately, as He endured suffering, He extended His wings, embraced His disciples, and carried them on His shoulders, proclaiming, 'I will extend My hands throughout the day to the faithless people' (Isaiah 65:2), to gather the children of Israel just as a hen gathers her chicks under her wings. Additionally, the stretching out of Moses' hands was pivotal for Israel's victory over Amalek (Ex. 17). Further references can be found in vv. 10.
