Exodus 5:16

ולבנים אמרים לנו AND BRICKS THEY — the taskmasters — SAY TO US עשו MAKE, just as the former number. וְחָטָאת עַמֶּךָ BUT THE FAULT IS IN THINE OWN PEOPLE — If the word וחטאת had the vowel Patach under the ט I would say that it is a noun in the construct state, so that the meaning would be, “and this thing is the sin of thy people” But now, since the vowel is Kametz, it is a noun in the absolute case, and its meaning is as follows: “And this thing brings sin upon thy people”, as though it were written וחטאת לעמך. Sirnilarly we find ל omitted in, (Ruth 1:19) “When they were come בית לחם” which is the same as לבית לחם, to Bethlehem, and there are many similar examples.

תֶּ֗בֶן אֵ֤ין נִתָּן֙ לַעֲבָדֶ֔יךָ וּלְבֵנִ֛ים אֹמְרִ֥ים לָ֖נוּ עֲשׂ֑וּ וְהִנֵּ֧ה עֲבָדֶ֛יךָ מֻכִּ֖ים וְחָטָ֥את עַמֶּֽךָ׃

There is no straw given to thy servants, and they say to us, Make bricks: and, behold, thy servants are beaten; but the fault is in thy own people.
