The first letter of the first line is a mirrored א

Second line

The second letter of the second line is an upside down ח or ת

The fourth fifth and sixth letter מצש has only one remote meaning in Hebrew which is מצ"ש - meaning the part of Saturday which is no longer considered Sabbath (after sundown).

The second line has only one letter which can be read as Hebrew which is מ as can be seen here

Third line

The second word is
