קְרָאתִ֥יךָ הוֹשִׁיעֵ֑נִי וְ֝אֶשְׁמְרָ֗ה עֵדֹתֶֽיךָ׃
I have called Thee, save me, and I will observe Thy testimonies.
Rashi on Psalms
and I shall keep (The acronym of, עֵדְוֹתֶיךָ is דמה בן פֶרֶץ ; the “vav” is vowelized with a “holam,” but in the other instances, it is עֵדֹתֶיךָ ; the “daleth” is vowelized with a “holam.”)
