אָֽנָּ֣ה יְהוָה֮ כִּֽי־אֲנִ֪י עַ֫בְדֶּ֥ךָ אֲֽנִי־עַ֭בְדְּךָ בֶּן־אֲמָתֶ֑ךָ פִּ֝תַּ֗חְתָּ לְמוֹסֵרָֽי׃
여호와여 나는 진실로 주의 종이요 주의 여종의 아들 곧 주의 종이라 주께서 나의 결박을 푸셨나이다
Rashi on Psalms
Your servant the son of Your maidservant There is no comparison between the training of a slave who was bought in the market and one who was born to a maidservant in the house.
Rashi on Psalms
You loosed my thongs You untied from my neck the bars and the thongs.
