What does Psalms Chapter 77 say, and which statements belong to its speaker?

The Latin incipit is Attendite. The heading describes benefits despite Israel's ingratitude. Understanding for Asaph calls attention to law, ears to words, future parables and beginning's propositions. The separate note interprets deep mysterious ancient facts as New Testament figures. Heard and known wonders were told by fathers and not hidden from children. Testimony and law commanded future generations taught so hope, memory and commandments replace perverse ancestors' unfaithfulness.

Ephraim's bowmen turned in battle, did not keep covenant or law and forgot benefits, without an added cowardice motive. Egyptian and Tanis wonders precede divided sea with waters as in a vessel, cloud by day, night fire and rock water flowing like rivers. They sinned further in the waterless place, sought desire's meat and asked whether God could supply table and bread despite water. Fire and wrath came because they did not believe or trust salvation. God had opened heaven, rained manna and abundant angels' bread. He removed south wind and brought south-west wind, not southeast, with flesh like dust and feathered fowls like sea's sand around camp and pavilions. Quail is not named here. They ate and received their desire, yet wrath slew fat ones and chosen men while meat was in mouth. Sin continued, days vanity and years haste.

When slain they sought and returned early, remembering helper and redeemer, but mouth love and tongue lies accompanied unfaithful hearts. God is merciful and will forgive and not destroy; many times He restrained anger, remembering flesh like a wind not returning. They repeatedly provoked, tempted and grieved Israel's Holy One, forgetting redemption from affliction.

The account returns to Egypt and Tanis: rivers and showers became blood, flies devoured and frogs destroyed, fruits went to blast and labors to locust. Hail ruined vines, hoarfrost mulberries, hail cattle and fire stock. Indignation and trouble came by evil angels, with souls and cattle not spared death and all Egypt's firstborn killed in Cham's tabernacles. God guided His people like a flock, in hope without fear while sea overwhelmed foes. He brought them to purchased sanctuary mountain, cast out Gentiles, distributed land by lot and line and housed tribes.

They again provoked, refused testimonies and covenant like crooked bow and gave jealousy with hills and graven things. God reduced Israel, put away Silo's tabernacle, gave strength and beauty to enemy captivity and people to sword. Fire consumed young men, maidens were not lamented, priests fell and widows did not mourn. The Lord awoke like one sleeping and a mighty man surfeited with wine, smote enemy hinder parts and gave lasting reproach. The text names neither a captured Ark nor Philistine opponents here. He rejected Joseph's tabernacle and Ephraim, chose Juda and loved Sion and built sanctuary as of unicorns. A separate note interprets firm horn-like strength and future church sanctuary. He chose David from sheep and pregnant ewes to feed Jacob and Israel; David fed with innocent heart and skillful hands.
