A little East of Jordan — Misunderstanding

A little East of Jordan, 1
Evangelists record,
A Gymnast and an Angel
Did wrestle long and hard-

Till morning touching mountain-5
And Jacob, waxing strong,
The Angel begged permission
To Breakfast-to return-

Not so, said cunning Jacob! 9
"I will not let thee go
Except thou bless me"-Stranger!
The which acceded to-

Light swung the silver fleeces 13
"Peniel" Hills beyond,
And the bewildered Gymnast
Found he had worsted God!
(F.145/J.59)
[1–16]:: This poem talks about Dickinson's view on Jacob and Peniel.
[3] Gymnast:: Jacob was good at wrestling like a gymnastic expert. Angel:: title of the pastor or minister of a church (OED 3, 1831); a church minister who blessed Jacob in line 11.
[6] Jacob:: a simpleton (OED 2c, 1811); a name close to Jason, hinted in line 13, silver (golden) fleece, a comparing of Bible to Greek myth.
[8] Breakfast:: the original word in Bible is breaketh, "Let me go, for the day breaketh." The priest wanted to have breakfast, not an angel.
[11] Stranger:: the man would not tell Jacob his name.
[13] silver fleeces:: the clothes worn by the priest, a hinted by Jason's golden fleece.
[14, 15] "Peniel", bewildered:: a mistaken of penil by bewildered Jacob, seen after the fleeces swung; or penile.
[16] he had worsted God:: the simpleton thought he had defeated God, but actually a priest.
