Sirach 9:15

“And the prophet, “he shall meditate in His Law day and night” ( Ps. i. 2 ), and again in another place, “Let all thy communication be in the law of the Most High.” ( Ecclus. ix. 15.)” — the author cites it

“And all the rest of thy time too adorn it with the rehearsing of the laws of God; “Yea, let all thy communication be in the law of the Most High.”” — editor's note: Ecclus. ix. 15.

“Further, eradicating frivolousness, beginning with God, it lays down the law for our regulation somewhat thus: “Do not repeat your words in your prayer.”” — editor's note: Ecclus. ix. 15.
