משך חכמה — ובקשתם משם את ה'... ומצאת

Q — Why does the pasuk shift from plural "ובקשתם" to singular "ומצאת"?

A — All Israel are one body when connected to the Center — Hashem; like radii meeting at the center of a circle, their unity flows from a common dveykus. When they sin and lose דבקות, they fragment from one another (plural). "ובקשתם" — in galut, they search as a fragmented many; but "ומצאת" — once they FIND Hashem and reconnect to the Center, they automatically reunify and are spoken of as one. אחדות ישראל depends on דבקות בה'.
