Lyrics and Translation
Part I
Im eshka'chech Yerushalayim -- Tishkach Yemini
If I forget Jerusalem -- Let my right hand forget its skill
Tidbak-Leshoni, Lechiki -- Im Loh Ezkerechi
Let my tongue cleave to my palate -- if I do not remember you
(Repeat Part I)
Part II
[Im Loh Yaaleh - x2], et Yerushalayim -- [Al Rosh Simchati x2]
[If I do not bring forth - x2], Jerusalem -- [at the beginning of my joy x2]
(Repeat Part II)
{Restart Part I and move to Part II}
