What does Daniel 11:30 mean?

For ships of Kittim shall come against him; therefore he shall be grieved, and shall return, and have indignation against the holy covenant, and shall do his pleasure: he shall even return, and have regard unto them that forsake the holy covenant.

For the ships of Chittim shall come against him: therefore he shall be grieved, and return, and have indignation against the holy covenant: so shall he do; he shall even return, and have intelligence with them that forsake the holy covenant.

For ships of Kittim shall come against him; therefore he shall be grieved, and shall return, and have indignation against the holy covenant, and shall do his pleasure: he shall even return, and have regard unto them that forsake the holy covenant.

For those who go out from the west will come against him, and he will be in fear and will go back, full of wrath against the holy agreement; and he will do his pleasure: and he will go back and be united with those who have given up the holy agreement.

And ships of Chittim have come in against him, and he hath been pained, and hath turned back, and hath been insolent toward the holy covenant, and hath wrought, and turned back, and he understandeth concerning those forsaking the holy covenant.

And the galleys and the Romans shall come upon him, and he shall be struck, and shall return, and shall have indignation against the covenant of the sanctuary, and he shall succeed: and he shall return, and shall devise against them that have forsaken the covenant of the sanctuary.

for ships of Chittim shall come against him; and he shall be grieved, and return, and have indignation against the holy covenant; and will practise; and he shall return and direct his attention to those that forsake the holy covenant.
