Contradiction with Genesis 32:24-30
Hosea 12:4 suggests Jacob "had power" with the angel and "prevailed," whereas Genesis describes Jacob wrestling with a man (interpreted as God) and implies the man allowed Jacob to prevail rather than being overpowered.
Genesis 32:24-30: And Jacob was left alone; and there wrestled a man with him until the breaking of the day. [breaking...: Heb. ascending of the morning]
Contradiction with Exodus 33:20
Hosea 12:4 refers to Jacob speaking with God, but Exodus 33:20 states no man can see God and live, which contradicts the notion of a direct encounter.
Exodus 33:20: And he said, Thou canst not see my face: for there shall no man see me, and live.
Contradiction with John 1:18
Hosea 12:4 implies Jacob saw and communicated with God face to face, whereas John says no one has seen God at any time, directly contradicting such an experience.
John 1:18: No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared [him].
Contradiction with 1 John 4:12
Similar to John 1:18, this verse states that no one has seen God at any time, contradicting the suggestion in Hosea 12:4 that Jacob saw God.
1 John 4:12: No man hath seen God at any time. If we love one another, God dwelleth in us, and his love is perfected in us.
