Genesis 32:28

‘Jacob’ may mean ‘one who cheats’. (See Genesis 25:26 and the comment.) ‘Israel’ probably means ‘God struggles’ or ‘he struggles with God’.

God said to Jacob, ‘You shall be called Israel.’ But after this time he had two names. He was sometimes called Israel and he was sometimes called Jacob. And even God called him Jacob. (See Genesis 46:2.) It was different for Abraham. He was initially called Abram. God said to him, ‘Now your name shall not be Abram. Your name shall be Abraham.’ (See Genesis 17:5.) And after that time he was only called Abraham. He was not called Abram.

v30 Jacob said, ‘I have seen God’s face. But I did not die.’ So he called that place Peniel. v31 The sun rose as Jacob passed through Penuel. He walked with one weak leg, because the man had touched his leg.

v32 Therefore even today Jacob’s *descendants do not eat the meat that is at the side of the leg. That is the place where the man touched Jacob’s leg.
